description: We continue the study of $n$-dependent groups, fields and related structures, largely motivated by the conjecture that every $n$-dependent field is dependent. We provide evidence towards this conjecture by showing that every infinite $n$-dependent valued field of positive characteristic is henselian, obtaining a variant of Shelah's Henselianity Conjecture in this case and generalizing a recent result of Johnson for dependent fields. Additionally, we prove a result on intersections of type-definable connected components over generic sets of parameters in $n$-dependent groups, generalizing Shelah's absoluteness of $G^{00}$ in dependent theories and relative absoluteness of $G^{00}$ in $2$-dependent theories. In an effort to clarify the scope of this conjecture, we provide new examples of strictly $2$-dependent fields with additional structure, showing that Granger's examples of non-degenerate bilinear forms over dependent fields are $2$-dependent. Along the way, we obtain some purely model-theoretic results of independent interest: we show that $n$-dependence is witnessed by formulas with all but one variable singletons; provide a type-counting criterion for $2$-dependence and use it to deduce $2$-dependence for compositions of dependent relations with arbitrary binary functions (the Composition Lemma); and show that an expansion of a geometric theory $T$ by a generic predicate is dependent if and only if it is $n$-dependent for some $n$, if and only if the algebraic closure in $T$ is disintegrated. An appendix by Martin Bays provides an explicit isomorphism in the Kaplan-Scanlon-Wagner theorem.

description: In this paper we extend the traditional ARCH(1) model by including a functional trend term in the conditional volatility of a time series. We derive the main properties of the model and apply it to all agricultural commodities in the Mexican CPI basket for three different time periods that implied changes in price regulations an behavior: pre-NAFTA (1987-1993), post-NAFTA (1994-2005)and commodity supercycle (2006-2014). The proposed model seems to adequately fit the volatility process and also outperforms, in the short run, the ARCH(1) and GARCH(1,1) models, some of the most popular approaches used in the literature to analyze price volatility. Our results show that, consistent with anecdotal evidence, price volatility trends of fruits and vegetables increased from the period 1987-1993 to 1994-2005, whereas they decreased for livestock products. From 1994-2005 to 2006-2014, fruits and vegetable trends decreased, whereas they increased for livestock products. Additionally, we identify some agricultural products that, due to their increasing price volatility trends, may present a risk for food inflation in the short run.

description: Die Analyse personenbezogener Daten kann dazu beitragen, datenbasierte Entscheidungen im Personalwesen zu treffen. Für viele Unternehmen stellt das sogenannte HR Analytics eine Möglichkeit dar, ihr Personalmanagement auf strategische Herausforderungen auszurichten, bemängeln aber, dabei vor Hürden zu stehen, um die Technologie zu integrieren. Die bestehende Fachliteratur zum Thema HR Analytics scheint nicht ausreichend, um die Zielgruppe auf die Besonderheiten bei der Erhebung und Auswertung von personenbezogenen Daten vorzubereiten. Das Ziel der vorliegenden Arbeit war es daher, ein optimiertes Vorgehensmodell zur Integration von Data Analytics im Personalwesen zu entwickeln. Dazu wurde der Forschungsansatz Design Science Research gewählt, um systematisch ein Artefakt zu konstruieren, dass die Probleme der Praxis lösen soll. Dabei ist in Zusammenarbeit mit Mitarbeitern aus dem HR- und IT-Bereich aus der Praxis ein digitaler Leitfaden entstanden, der detaillierte Lösungsansätze zum Abbau der Hürden bereitstellt. Um den Praxisnutzen des Leitfadens zu bestimmen, wurde abschließend eine Demonstration und Begutachtung mit einer HRA-Expertin durchgeführt.

In the model, the tiny observed positive cosmological constant is interpreted as a curvature of 5-dimensional manifold, but the Minkowski spacetime, where we live, is a natural 3-brane perpendicular to the fifth coordinate axis.

description: Bright and dark spatial solitons are observed in an optically pumped semiconductor resonator. The pumping allows to considerably reduce the light intensity necessary for the existence of the solitons and alleviates thermal load problems. Experiments are found to agree with calculations based on a simple large aperture semiconductor resonator model. The role of signs of the absorptive and reactive nonlinearities for soliton existence are discussed in relation with the nonlinear resonance effect, the tilted wave mechanism of pattern formation, and the sign of the population inversion.

description: We examine how various producer-level and farm-level factors affect producers' support for marketing orders, focusing on the California fresh peach and nectarine industries and the 2011 referendum vote in which their marketing orders were terminated. We form hypotheses regarding the effects of different factors. We then employ marketing order referendum voting data and additional data collected via a producer survey to test these hypotheses empirically. Some of our results conform to our predictions. For example, we find that producers with greater production of peaches and nectarines were less likely to vote for continuance of the marketing order. However, some results did not conform to our predictions. We found that gross income from farming and related activities to be insignificant and producers with some organic production or some direct sales are both more likely to vote for continuation. Our results suggests important dimensions of differentiation between producers for policymakers, regulators and industries to consider as they ponder the future of marketing orders.

description: This study proposes a deep learning model that effectively suppresses the false alarms in the intensive care units (ICUs) without ignoring the true alarms using single- and multimodal biosignals. Most of the current work in the literature are either rule-based methods, requiring prior knowledge of arrhythmia analysis to build rules, or classical machine learning approaches, depending on hand-engineered features. In this work, we apply convolutional neural networks to automatically extract time-invariant features, an attention mechanism to put more emphasis on the important regions of the input segmented signal(s) that are more likely to contribute to an alarm, and long short-term memory units to capture the temporal information presented in the signal segments. We trained our method efficiently using a two-step training algorithm (i.e., pre-training and fine-tuning the proposed network) on the dataset provided by the PhysioNet computing in cardiology challenge 2015. The evaluation results demonstrate that the proposed method obtains better results compared to other existing algorithms for the false alarm reduction task in ICUs. The proposed method achieves a sensitivity of 93.88% and a specificity of 92.05% for the alarm classification, considering three different signals. In addition, our experiments for 5 separate alarm types leads significant results, where we just consider a single-lead ECG (e.g., a sensitivity of 90.71%, a specificity of 88.30%, an AUC of 89.51 for alarm type of Ventricular Tachycardia arrhythmia)
Fracton pairing mechanism for "strange" superconductors: Self-assembling organic polymers and copper-oxide compounds

Publisher: name: arXiv
Year: 2002
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Self-assembling organic polymers and copper-oxide compounds are two classes of "strange" superconductors, whose challenging behavior does not comply with the traditional picture of Bardeen, Cooper, and Schrieffer (BCS) superconductivity in regular crystals. In this paper, we propose a theoretical model that accounts for the strange superconducting properties of either class of the materials. These properties are considered as interconnected manifestations of the same phenomenon: We argue that superconductivity occurs in the both cases because the charge carriers (i.e., electrons or holes) exchange {\it fracton excitations}, quantum oscillations of fractal lattices that mimic the complex microscopic organization of the strange superconductors. For the copper oxides, the superconducting transition temperature $T_c$ as predicted by the fracton mechanism is of the order of $\sim 150$ K. We suggest that the marginal ingredient of the high-temperature superconducting phase is provided by fracton coupled holes that condensate in the conducting copper-oxygen planes owing to the intrinsic field-effect-transistor configuration of the cuprate compounds. For the gate-induced superconducting phase in the electron-doped polymers, we simultaneously find a rather modest transition temperature of $\sim (2-3)$ K owing to the limitations imposed by the electron tunneling processes on a fractal geometry. We speculate that hole-type superconductivity observes larger onset temperatures when compared to its electron-type counterpart. This promises an intriguing possibility of the high-temperature superconducting states in hole-doped complex materials. A specific prediction of the present study is universality of ac conduction for $T\gtrsim T_c$.

description: Die Freisetzung von leichtflüchtigen organischen Kohlenstoffverbindungen (VOCs) und deren Bedeutung als Vorläufersubstanzen zur Bildung von Feinstaub und Ozon sind vor allem in den Ballungs- und Industriegebieten Chinas ein großes Problem. Gerade bei Industrieprozessen in denen große Mengen dieser VOCs erzeugt werden ist eine Abreinigung und mögliche Rückgewinnung dieser Substanzen zielführend. Im Vergleich zu Europa ist China ein Spätstarter bei der Kontrolle von VOCs. Von 2010 bis heute wurde eine Reihe von nationalen Maßnahmen zur strengen Kontrolle von VOCs eingeführt. Derzeit gibt es für die Behandlung von organischen Abgasen hauptsächlich Absorption, Adsorption, biologische Methoden, Verbrennung etc. Aber für halogenierte Kohlenwasserstoffe VOC (wie Dichlormethan, Dichlorethan usw.) kann die Verbrennungsmethode der Behandlung nicht verwendet werden. Daher wird in diesem Projekt die Adsorptionsverfahren mit hypervernetztem Harz als Adsorptionsmittel für die Adsorption und Rückgewinnung von halogenierten Kohlenwasserstoff-VOCs aus organisierten Emissionen verwendet. Während der Planung liegt die Hauptaufgabe auf der Bestimmung der Parameter der einzelnen Einheiten und dem Entwurf der Abmessungen des Adsorptionsreaktors und der Höhe der Packung und schließlich der Verbindung der Strukturen der Einheiten

description: This study evaluates the efficiency gains in forecasting three commodity prices (live cattle, coffee and cotton) using time series models. Different leves of temporal aggregations are tested (weekly, monthly, quarterly and annually). The objective is to test whether models based on disaggregated data can produce better price forecasting than the corresponding model using a higher level of aggregation. For example, we test if weekly models can predict better monthly prices than monthly models. Because the high volatility in real prices, we evaluate the possible non-stationarity behavior and heteroskedasticity of each commodity. Then, we use time series methods to model the prices and select the best estimators at each aggregation level and commodity. For the three commodity prices, models based on disaggregated levels effectively provided an efficiency gain in forecasting. Among these levels, the best models were the weekly models. The same behavior was consistent across all possible levels of aggregations.

Fueling Local Water Pollution: Ethanol Refineries, Land Use, and Nitrate Runoff

description: Ethanol production in the United States, driven by federal renewable fuel policy, has exploded over the past two decades and has prompted the construction of many ethanol refineries throughout the US Corn Belt. These refineries have introduced a new inelastic demand for corn in the areas where they were built, reducing basis for nearby farmers and effectively subsidizing local corn production. In this paper, I explore whether and to what extent the construction of new ethanol refineries has actually increased local corn acreage. I also explore some environmental effects of this acreage increase. Using a thirteen year panel of over two million field-level observations in Illinois, Indiana, Iowa, and Nebraska, I estimate a net increase of nearly 300,000 acres of corn in 2014 relative to 2002 that can be attributed to the placements of new ethanol refineries. This increase comprises approximately 0.75% of the total 2014 corn acreage within my dataset. Furthermore, this effect is separate from the general equilibrium effect of ethanol policy increasing aggregate demand for corn. Back-of-the-envelope calculations suggest that over 21,000 tons of the nitrogen applied to fields in my sample in 2014 can be attributed to refinery location effects. Essentially all of these observed effects occur only in areas within 30 miles of an ethanol refinery, suggesting that refineries have meaningful localized impacts on land use and environmental quality such as nitrate runoff.

description: In the context of the Hamiltonian formulation of the teleparallel equivalent of general relativity we compute the gravitational energy of Kerr and Kerr Anti-de Sitter (Kerr-AdS) space-times. The present calculation is carried out by means of an expression for the energy of the gravitational field that naturally arises from the integral form of the constraint equations of the formalism. In each case, the energy is exactly computed for finite and arbitrary spacelike two-spheres, without any restriction on the metric parameters. In particular, we evaluate the energy at the outer event horizon of the black holes.

description: We compute the Euclidean actions of a $d$-dimensional charged rotating black brane both in the canonical and the grand-canonical ensemble through the use of the counterterms renormalization method, and show that the logarithmic divergencies associated with the Weyl anomalies and matter field vanish. We obtain a Smarr-type formula for the mass as a function of the entropy, the angular momenta, and the electric charge, and show that these quantities satisfy the first law of thermodynamics. Using the conserved quantities and the Euclidean actions, we calculate the thermodynamics potentials of the system in terms of the temperature, angular velocities, and electric potential both in the canonical and grand-canonical ensembles. We also perform a stability analysis in these two ensembles, and show that the system is thermally stable. This is commensurate with the fact that there is no Hawking-Page phase transition for a black object with zero curvature horizon. Finally, we obtain the logarithmic correction of the entropy due to the thermal fluctuation around the equilibrium.

description: This paper studies spatial price transmission and integration of regional domestic wheat markets in Russia. An innovative approach to threshold estimation is applied to better capture model non-linearities associated with transaction costs and policy measures. The results show critical importance of distance that determines the speed at which price shocks are transmitted between the regional markets. Additionally, it is shown that the export ban for wheat in 2010/11 led to trade activation and faster price transmission inside the country. The effect of export ban was found to be enhanced by transport subsidies introduced to facilitate the distribution of grain in the wake of severe drought in certain production areas.
Fermi-Hubbard model on non-bipartite lattices: flux problem and emergent chirality

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: On several one-dimensional (1D) and 2D nonbipartite lattices, we study both free and Hubbard interacting lattice fermions when some magnetic fluxes are threaded or gauge fields coupled. First, we focus on finding out the optimal flux which minimizes the energy of fermions at specific fillings. For spin-$1/2$ fermions at half-filling on a ring lattice consisting of odd-numbered sites, the optimal flux turns out to be $\pmπ/2$. We prove this conclusion for Hubbard interacting fermions utilizing a generalized reflection positivity technique, which can lead to further applications on 2D nonbipartite lattices such as triangular and Kagome. At half-filling the optimal flux patterns on the triangular and Kagome lattice are ascertained to be $\pm[π/2,π/2]$, $\pm[π/2,π/2,0]$, respectively (see the meaning of these notations in the main text). We also find that chirality emerges in these optimal flux states. Then, we verify these exact conclusions and further study some other fillings with the numerical exact diagonalization method. It is found that when it deviates from half-filling, Hubbard interactions can alter the optimal flux patterns on these lattices. Moreover, numerically observed emergent flux singularities driven by strong Hubbard interactions in the ground states, both in 1D and 2D, are discussed and interpreted as some kind of non-Fermi liquid feature.

That is, one can hear the shape of the graph! We also consider a related inversion problem: A compact graph can be converted into a scattering system by attaching to its vertices leads to infinity. We show that the scattering phase determines uniquely the compact part of the graph, under similar conditions as above.

description: Cross and Buccola (2004) established that if the lenders of cooperatives are not in position to assess the “right” price to be paid for the raw-material delivered by cooperative members, these latter may push for a cash transfer which may deteriorate the financial position of the cooperative. This form of liquidation can be an exit way for cooperatives which, at the turning point of maturity, do not seek strategic alliances to increase their market power, or do not shift to a new model, according to the lifecycle approach of Cook (1995). In this research, we test this hypothesis for cooperatives of the Bordeaux wine industry. We run two regression which aim at characterizing the relationship between leverage and cash transfer to cooperative members according to the downstream strategy of cooperatives. Our results confirm our main hypothesis. The cooperatives which stay in the traditional form are prone to liquidation: the cash transfer to producers implies a higher leverage which implies a financial distress. The financial behavior of cooperatives forming union and of those which have opted for vertical integration is radically different.

Am stärksten betroffen sind die Sprachentwicklung, sowie die Grob- und entsprechend die Fein-Motorik. Im 1. Lebensjahr bestehen ausgeprägte Fütterungsprobleme, Gedeihprobleme und Infektionen (u.a. Mittelohrentzündungen). Im weiteren Verlauf stehen weiterhin massives Erbrechen, Darmverstopfung und Schlafstörungen im Vordergrund; hinzukommen orthopädische Probleme wie Fußfehlstellungen und Skoliose. Ein großes Problem für die Sozialisierung sind die ausgeprägten Schwierigkeiten bei der (Laut-)Sprachentwicklung.

description: A recent review of ERS’s productivity accounts recommended that ERS treat dairy cows, breeding beef cows and other long‐lived working animals as capital assets (Shumway, et. al 2014). BEA was also given the same recommendation in the international guidelines for national accounts, System of National Accounts 2008 (SNA 2008). In ERS’s farm accounts and BEA’s National Income and Product Accounts (NIPA’s), long‐lived working animals are currently treated as an inventory asset. This paper recalculates the farm accounts and NIPA’s when long‐lived working animals are re‐classified as a capital asset. We show that this reclassification raises farm output and GDP for every year – but the increase is larger for earlier years. As a result, real farm output growth and real GDP growth falls slightly when long‐lived working animals are capitalized. Total factor productivity (TFP) growth falls slightly from 1.42% per year to 1.38% per year when year when long‐lived working animals are capitalized.

Effects of the modification of gravity on the production of primordial black holes

description: The enhancement of the spectrum of primordial comoving curvature perturbation $\R$ can induce the production of primordial black holes (PBH) which could account for part of present day dark matter. As an example of the effects of the modification of gravity on the production of PBHs, we investigate the effects on the spectrum of $\R$ produced by the modification of gravity in the case of G-inflation, deriving the relation between the unitary gauge curvature perturbation $ζ$ and the comoving curvature perturbation $\R$, and identifying a background dependent enhancement function $\E$ which can induce large differences between the two gauge invariant variables. We use this relation to derive an equation for $\R$, showing for the presence of a momentum dependent effective sound speed (MESS), associated to the intrinsic entropy which can arise in modified gravity theories, in agreement with the model independent MESS approach to cosmological perturbations. When $ζ$ is not constant in time it is different from $\R$, for example on sub-horizon scales, or in models exhibiting an anomalous super-horizon growth of $ζ$, but since this growth cannot last indefinitely, eventually they will coincide. We derive the general condition for super-horizon growth of $ζ$, showing that slow-roll violation is not necessary. Since the abundance of PBHs depends on the statistics of the peaks of the comoving density contrast, which is related to the spectrum of $\R$, it is important to take into account these effects on the PBHs abundance in modified gravity theories.

description: The island of Nias/Indonesia shows an extremely reduced genetic diversity indicating a strong founder effect. One such disorder that can easily be ascertained during field research is albinism. All over the island, probands with albino phenotype were screened for OCA mutations. A novel homozygous tyrosinase mutation c.701C>T was identified in all four probands studied from very distinct parts of the island. The observed prevalence was 1 in 3,260. We argue that clinical genetics and mutation mapping can add to the combined power of population genetics, linguistics, and archeology for subsequent studies on the origin and migration of a given population. In our example mutation testing for tyrosinase exchange c.701C>T in probands outside Nias might be helpful in tracing the potential homelands of the Niassians. So far, candidate regions highly suggestive by population genetic and by comparative linguistic studies are Sangir Islands, Philippines and Taiwan.

description: This paper aims at improving the application of the learning curve, a popular tool used for forecasting future costs of renewable technologies in integrated assessment models (IAMs). First, we formally discuss under what assumptions the traditional (OLS) estimates of the learning curve can deliver meaningful predictions in IAMs. We argue that the most problematic of them is the absence of any effect of technology cost on its demand (reverse causality). Next, we show that this assumption can be relaxed by modifying the traditional econometric method used to estimate the learning curve. The new estimation approach presented in this paper is robust to the reverse causality problem but preserves the reduced form character of the learning curve. Finally, we provide new estimates of learning curves for wind turbines and PV technologies which are tailored for use in IAMs. Our results suggest that the learning rate should be revised downward for wind power, but possibly upward for solar PV.

description: Human economies and ecosystems form a coupled system coevolving in time and space, since human economies use ecosystems services and at the same time affect ecosystems through their production and consumption activities. The study of the interactions between human economies and ecosystems is fundamental for the efficient use of natural resources and the protection of the environment. This necessitates the development and use of models capable of tracing the main interactions, links and feedbacks. In developing this chapter, our objective was to focus on a segment of rapidly developing literature on coupled ecological/economic models with an emphasis on climate change. The advantage of this approach is that it introduces the reader to a very important current research topic, but it also allows, by using climate as the reference ecosystem, the exploration of new modeling approaches which are relevant and useful for the modeling of other types of coupled ecological/economic systems. These include modeling of deep structural uncertainty by using robust control methods, exploring modeling through cumulative carbon budgeting, studying spatial transport phenomena and spatial aspects in economic/ecological modelling.

description: COMPARATIVE ANALYSIS OF OOSPORES OF CHARA BAUERI AND CHARA BRAUNII
In Figure 7, Chara baueri and Chara braunii are shown in relation to the measured oospore parameters. The analysis (F = 6.3, P = 0.002) described 27% variability in our data. Oospore parameters AND, LPA, ISI and number of ridges were positively correlated with Chara baueri, while LED and width of fossa showed positive correlation with Chara braunii, meaning that Chara baueri is characterized by longer, somewhat narrower, and more prolate oospores compared to those of C. braunii. Also in C. baueri the number of ridges was higher and they were more compactly arranged (narrower fossa). The correlation of ANI was almost nonexistent when both species were considered.
CLUSTER ANALYSES OF OOSPORE PARAMETERS
Cluster analysis results presented in Figure 8 confirm the potential of applying oospores and their features in species delineation by means of unsupervised machine learning.
The results of hierarchical clustering that was applied on the sample median values for all oospore parameters also confirmed the separation of samples into four separate clusters that matched individual taxa (Fig. 8).

description: We define a 3-generator algebra obtained by replacing the commutators by anticommutators in the defining relations of the angular momentum algebra. We show that integer spin representations are in one to one correspondence with those of the angular momentum algebra. The half-integer spin representations, on the other hand, split into two representations of dimension j + 1/2. The anticommutator spin algebra is invariant under the action of the quantum group SO_q(3) with q=-1.
