description: A Cobb-Douglas stochastic frontier function is estimated for the cow-calf enterprises in the Texas Rolling Plains using Standardized Performance Analysis (SPA) data. We find that factors promoting higher herd productivity include machinery investment, pasture-quality improvement, and protein supplement. In contrast, herd productivity is compromised by a longer breeding season, percentage of hired labor, and deviation from mean annual rainfall. Interestingly, more technically efficient farms tend to emit fewer greenhouse gas units per unit of output. For example, net greenhouse gas emissions are 6.12 and -8.70 pounds of carbon equivalent, respectively, for farms with technical efficiency below 0.8 and above 0.96.

description: Electronic transport properties of Au nano-structure are investigated using both experimental and theoretical analysis. Experimentally, stable Au nanowires were created using mechanically controllable break junction in air, and simultaneous current-voltage (I-V) and differential conductance $δI/δV$ data were measured. The atomic device scale structures are mechanically very stable up to bias voltage $V_b\sim0.6V$ and have a life time of a few $minutes$. Facilitated by a shape function data analysis technique which finger-prints electronic properties of the atomic device, our data show clearly differential conductance fluctuations with an amplitude $>1%$ at room temperature, and a nonlinear I-V characteristics. To understand the transport features of these atomic scale conductors, we carried out {\it ab initio} calculations on various Au atomic wires. The theoretical results demonstrate that transport properties of these systems crucially depend on the electronic properties of the scattering region, the leads, and most importantly the interaction of the scattering region with the leads. For ideal, clean Au contacts, the theoretical results indicate a linear I-V behavior for bias voltage $V_b<0.5V$. When sulfur impurities exist at the contact junction, nonlinear I-V curves emerge due to a tunnelling barrier established in the presence of the S atom. The most striking observation is that even a single S atom can cause a qualitative change of the I-V curve from linear to nonlinear. A quantitatively favorable comparison between experimental data and theoretical results is obtained. We also report other results concerning quantum transport through Au atomic contacts.

description: The linear span P_n of the sums of all permutations in the symmetric group S_n with a given set of peaks is a sub-algebra of the symmetric group algebra, due to Nyman. This peak algebra is a left ideal of the descent algebra D_n; and the direct sum P of all P_n is a Hopf sub-algebra of the direct sum D of all D_n, dual to the Stembridge algebra of peak functions. In our self-contained approach, peak counterparts of several results on the descent algebra are established, including a simple combinatorial characterization of the algebra P_n; an algebraic characterization of P_n based on the action on the Poincar'e-Birkhoff-Witt basis of the free associative algebra; the display of peak variants of the classical Lie idempotents; an Eulerian-type sub-algebra of P_n; a description of the Jacobson radical of P_n and its nil-potency index, of the principal indecomposable and irreducible P_n-modules, and of the Cartan matrix of P_n. Furthermore, it is shown that the primitive Lie algebra of P is free, and that P is its enveloping algebra.

description: En este estudio se estima el valor de uso activo actual de cinco espacios naturales protegidos de Córdoba y Jaén a través del hipotético pago de una entrada por la visita al parque. Dentro del enfoque de la valoración contingente hemos optado por el formato de pregunta abierta y la entrevista personal como procedimiento de la encuesta. Se realizaron un total de 400 entrevistas en cada ENP, permitiendo cuantificar la relación entre la disposición a pagar una entrada y el resto de variables de tipo socioeconómico y de localización. Los resultados sugieren una disposición media a pagar una entrada que va desde los 4,28 euros hasta los 2,24. El modelo econométrico que explica la disposición a pagar tiene como variables explicativas la localización, es decir, el parque en cuestión, los ingresos familiares mensuales, la edad y el nivel de estudios del encuestado, estas dos últimas negativamente correlacionados con dicha disposición...This empirical work follows the contingent valuation methodology to estimate the willingness to pay for entrance to five natural protected areas located in two provinces of Southern Spain. The bid vehicle elicits user values for the parks through an open-ended question. The survey was administered by face-to-face interviews, with a total of 1,229 cases. It is proposed a semilog model to explain the stated payment as a function of location, income, education and age. The model makes sense in terms of both explanatory power and prior expectation on explaining variables.

description: We study various properties of bosons in two dimensions interacting only via onsite hardcore repulsion. In particular, we use the lattice spin-wave approximation to calculate the ground state energy, the density, the condensate density and the superfluid density in terms of the chemical potential. We also calculate the excitation spectrum, $ω({\bf k})$. In addition, we performed high precision numerical simulations using the stochastic series expansion algorithm. We find that the spin-wave results describe extremely well the numerical results over the {\it whole} density range $0\leq ρ\leq 1$. We also compare the lattice spin-wave results with continuum results obtained by summing the ladder diagrams at low density. We find that for $ρ\leq 0.1$ there is good agreement, and that the difference between the two methods vanishes as $ρ^2$ for $ρ\to 0$. This offers the possibility of obtaining precise continuum results by taking the continuum limit of the spin-wave results for all densities. Finaly, we studied numerically the finite temperature phase transition for the entire density range and compared with low density predictions.

description: The systematics of energy staggering for the magnetic rotational bands with $M1$ and $E2$ transition properties strictly consistent with the features of good candidates of magnetic rotational bands in the $A\sim80$, 110, 130 and 190 mass regions are presented. The regularities exhibited by these bands concerning the staggering parameter which increases with increasing spin are in agreement with the semiclassical description of shears mechanism. In addition, the abnormal behaviours in the backbend regions or close to band termination have also been discussed. Taking the magnetic dipole bands with same configuration in three $N=58$ isotones, i.e., $^{103}$Rh, $^{105}$Ag, and~$^{107}$In, as examples, the transition from chiral rotation to magnetic rotation with the proton number approaching $Z=50$ is presented. Moreover, the self-consistent tilted axis cranking and principle axis cranking relativistic mean-field theories are applied to investigate the rotational mechanism in dipole band of $^{105}$Ag.

We list the 416 BCGs identified as part of this process, along with their stellar mass, star formation rates, and morphological properties. We identified the BCGs based on the available spectroscopic data from SPIDERS and photometric data from SDSS. We computed stellar masses and SFRs of the BCGs on the basis of SDSS, WISE, and GALEX photometry using spectral energy distribution fitting. Morphological properties for all BCGs were derived by Sersic profile fitting using the software package SIGMA in different optical bands (g,r,i). We combined this catalog with the BCGs of galaxy groups and clusters extracted from the deeper AEGIS, CDFS, COSMOS, XMM-CFHTLS, and XMM-XXL surveys to study the stellar mass - halo mass relation using the largest sample of X-ray groups and clusters known to date. This result suggests that the mass growth of the central galaxy is controlled by the hierarchical mass growth of the host halo. We find a strong correlation between the stellar mass of BCGs and the mass of their host halos. This relation shows no evolution since z $\sim$ 0.65. We measure a mean scatter of 0.21 and 0.25 for the stellar mass of BCGs in a given halo mass at low ( $0.1

description: Records of rental agreements for agricultural land in England between 1690 and 1914 are used to develop an annual rental price index for agricultural land. This index displays a long run cointegrating relationship with indices for the price of agricultural output and agricultural wage rates. A vector error correction model illustrates the powerful long run causal influence of the price of agricultural output and wage rates on rents. By contrast, there is no evidence that rents cause wage rates or the price of agricultural output. Such results suggest that Ricardo was right when he posited that rent was a residual driven by increases in the price of agricultural output rather than the other way around. Matters are different however when the price of individual agricultural commodities is used rather than the price of agricultural output. In this situation there emerges a bidirectional causal relationship of the type envisaged by Jevons. Lastly our framework can also be used to measure the rate of technical progress in agriculture. While we cannot find a statistically significant level of technical progress before the industrial revolution, after 1785 the rate of technical progress is a brisk 1.8 percent per annum.

description: Agriculture makes a significant contribution to Norway’s emissions of greenhouse gases (GHG). Although the sector accounts for only 0.3 per cent of GDP, it accounts for roughly 9 per cent of total GHG emissions. Norwegian agriculture is dominated by livestock production; ruminants (cattle and sheep) are particularly important. There are opportunities for GHG mitigation under existing technology through changes in agricultural practices. Analytically we derive abatement cost curves for Norway in terms of the change in economic welfare, and on a theoretical basis we examine the impact of various policy objectives on the abatement cost curve. In particular we consider the policy objective of keeping the production of calories at the current level. We use a detailed economic model to assess the impact and welfare implication of a reduction in GHG emissions.

description: The existence of dark matter particles that carry phenomenologically relevant self-interaction cross sections mediated by light dark sector states is considered to be severely constrained through a combination of experimental and observational data. The conclusion is based on the assumption of specific dark matter production mechanisms such as thermal freeze-out together with an extrapolation of a standard cosmological history beyond the epoch of primordial nucleosynthesis. In this work, we drop these assumptions and examine the scenario from the perspective of the current firm knowledge we have: results from direct and indirect dark matter searches and cosmological and astrophysical observations, without additional assumptions on dark matter genesis or the thermal state of the very early universe. We show that even in the minimal set-up, where dark matter particles self-interact via a kinetically mixed vector mediator, a significant amount of parameter space remains allowed. Interestingly, however, these parameter regions imply a meta-stable, light mediator, which in turn calls for modified search strategies.

description: In this paper the dynamic information flows among monthly prices of agricultural commodities in the United States (U.S.) and Mexico for the years 2000-2012 are analysed. Error correction models and directed acyclical graphs are employed with observational data to identify the dynamic relationships among prices for important agricultural commodities in both countries. Unlike previous studies, results here indicate the existence of long-run relationships among prices. Results suggest that commodity prices in the U.S. market are highly influenced by their own historical innovations, while U.S. grain prices have a consistently strong impact on price movements in Mexican agricultural markets in the longrun. Further, information flows among grain markets in Mexico and from grain to cattle markets are also identified and described.

description: UV radiation can affect the physiology of seaweeds and their associated microorganisms. In this study we exposed different Chilean populations of the agarophyte Gelidium lingulatum to PAR or PAR+UV and monitored their photosynthetic performance using in vivo chlorophyll fluorescence for 5 days to determine changes in abundance and composition of epibiotic bacteria. Before the experiment, the seaweeds had been acclimated for more than 1 year in outdoor tanks with flowing seawater. At the beginning of the experiment, maximum quantum yield (Fv/Fm) did not vary among different populations. During the recovery period, Fv/Fm increase was higher in thalli from La Pampilla (30°S) in comparison with other populations (33°S and 42°S). The lowest total amount of bacteria (22.2 ± 2.5 × 103 cell mm–2) on thalli was observed at the beginning of the experiment. At the end of the experiment, the density of bacteria was not significantly different among thalli from different populations, as well as among UV-exposed and non-exposed seaweeds. The bacterial community in seawater was different from that on the seaweed thalli as shown by MiSeq Illumina reads of 16S rRNA. UV exposure changed the composition of microbial communities on the thalli and led to a reduction in community diversity and evenness. Relative abundance of Alteromonas sp. increased but abundances of Methylophaga sp. and Colwellia sp. decreased during UV exposure. Microbes associated with G. lingulatum may play an important ecological role in seaweed-microbial interactions. Future studies should explore the ecological function of microbial communities associated with seaweeds.

description: We present a careful recasting of first-principles band structure calculations for MgB2 in a non-orthogonal sp-tight-binding (TB) basis. Our TB results almost exactly reproduce our full potential linearized augmented plane wave results for the energy bands, the densities of states and the total energies. Our procedure generates transferable Slater-Koster parameters which should be useful for other studies of this important material.

Self-organized bistability and its possible relevance for brain dynamics

description: Self-organized bistability (SOB) is the counterpart of 'self-organized criticality' (SOC), for systems tuning themselves to the edge of bistability of a discontinuous phase transition, rather than to the critical point of a continuous one. The equations defining the mathematical theory of SOB turn out to bear strong resemblance to a (Landau-Ginzburg) theory recently proposed to analyze the dynamics of the cerebral cortex. This theory describes the neuronal activity of coupled mesoscopic patches of cortex, homeostatically regulated by short-term synaptic plasticity. The theory for cortex dynamics entails, however, some significant differences with respect to SOB, including the lack of a (bulk) conservation law, the absence of a perfect separation of timescales and, the fact that in the former, but not in the second, there is a parameter that controls the overall system state (in blatant contrast with the very idea of self-organization). Here, we scrutinize --by employing a combination of analytical and computational tools-- the analogies and differences between both theories and explore whether in some limit SOB can play an important role to explain the emergence of scale-invariant neuronal avalanches observed empirically in the cortex. We conclude that, actually, in the limit of infinitely slow synaptic-dynamics, the two theories become identical, but the timescales required for the self-organization mechanism to be effective do not seem to be biologically plausible. We discuss the key differences between self-organization mechanisms with/without conservation and with/without infinitely separated timescales. In particular, we introduce the concept of 'self-organized collective oscillations' and scrutinize the implications of our findings in neuroscience, shedding new light into the problems of scale invariance and oscillations in cortical dynamics.

description: This article evaluates the impact of an extension programme that financially rewards farmers for participation. The evaluation focuses on programme participants who joined after a financial reward was introduced and compares their farm performance to farmers who chose not to join the programme. Farmers are assessed in relation to improvements in financial, grassland and breeding management over an observation period from 2008 and 2012. The results, based on a modified difference-in-difference estimator, reveal no significant impact of the programme, albeit programme participants seem to have improved their farm performance. Reasons for this finding are discussed and, given this rather unique policy move, the study offers policy recommendations of broad relevance.

description: Results on the study of localized fluctuations in the multiplicity of charged particles and photons produce 158A GeV/c Pb+Pb collisions are presented for four different centrality classes. The charged versus neutral particle multiplicity correlations in common phase space regions of varying azimuthal size are analyzed by two different methods. Various types of mixed events are constructed to probe fluctuations arising from different sources. The measured results are compared to those from simulations and from mixed events. The comparison indicates the presence of non-statistical fluctuations in both the charged particle and photon multiplicities in limited azimuthal regions which decrease with decrease in centrality. However, no correlated charged-neutral fluctuations, a possible signature of formation of disoriented chiral condensates, are observed. An upper limit on the production of disoriented chiral condensates has been set.

description: We establish spreading properties of the Lotka-Volterra competition-diffusion system. When the initial data vanish on a right half-line, we derive the exact spreading speeds and prove the convergence to homogeneous equilibrium states between successive invasion fronts. Our method is inspired by the geometric optics approach for Fisher-KPP equation due to Freidlin, Evans and Souganidis. Our main result settles an open question raised by Shigesada et al. in 1997, and shows that one of the species spreads to the right with a nonlocally pulled front.

description: This study builds on recent treatments of the marine red algal family Gracilariaceae (Gracilariales) focusing in detail on Hydropuntia and Crassiphycus. Species in these two genera often present identification problems due to high levels of morphologial similarity among genetically distinct species, and high levels of phenotypic plasticity, leading to pseudo-cryptic speciation and homoplasies. In order to resolve long standing problems, clarify some species concepts and better understand the evolution of the group, we performed phylogenetic analyses of all plastid rbcL DNA sequences available for known Hydropuntia and Crassiphycus species, including newly sequenced specimens. Our results revealed the presence of potentially undescribed species, the existence of strong phylogeographic patterns below and above the species level and helped re-delineate morphologically similar taxa. New detailed morphological descriptions for three common yet poorly known Western Atlantic species are provided: C. secundus, C. usneoides and H. rangiferina. H. rangiferina from the Indo-Pacific is a distinct species from the true H. rangiferina and represents a putative undescribed species. We also provide a time-calibrated phylogeny for the six genera in the Gracilariales to identify past geological and climatic processes associated with their origin and diversification.

description: Pesticides efficiency decreases with their global application by farmers. Within a strategic dynamic framework, this results in a classic intertemporal production externality. We analyze tax and subsidy schemes that can be used in order to internalize this externality. We show that they are able to restore socially optimal paths but that final time of pesticide use differs. With these schemes, farmers have a tendency to switch to alternative pest-control technology, as integrated pest management, earlier than is optimal. A lump-sum transfer is shown to be necessary to obtain a switching time equal to the socially optimal one, for the subsidy case only. Furthermore, the socially optimal switching time can be later than the one obtained under a situation without control.

The Fine-Structure Constant from Recursive Geometry: A First-Principles Derivation

description: This paper derives the fine-structure constant \( \alpha \approx 1/137.035999 \) from recursive angular geometry and coherence thresholds, without fitting, empirical tuning, or quantum field assumptions.

Using only mathematical constants — \( \pi \) (rotational closure), \( \phi \) (the golden ratio), and a structural impedance factor \( k = 3.4 \) — we derive the expression:\[\alpha = \frac{1}{k \pi \phi^2}\]and show that it matches the CODATA value to within one part in ten million.

An independent derivation from the proton–electron mass ratio yields:\[\alpha = \frac{\pi \phi^3 \cdot \lambda}{m_p / m_e}\]where \( \lambda \approx 0.99988 \) emerges as a recursive coherence correction factor from analog phase retention modeling.

These two derivations — one angular, one mass-based — converge on the same value and reveal a closed structural identity:\[\alpha = \frac{1}{k \pi \phi^2} = \frac{X \cdot \lambda}{m_p / m_e}, \quad X = \pi \phi^3\]

We interpret α not as a coupling parameter, but as the fractional release of coherence per recursive cycle — a structural threshold necessary for recursion to stabilize across curvature.

This work is part of the Coherence Trilogy, a series exploring foundational constants from geometric first principles in collaboration with ~GPT-4o as co-intelligence.
