description: This paper assesses the efficiency and performance of organic alfalfa farms. Data were obtained from questionnaires collected from forty farms participating in an EU-subsidized program promoting the switch to organic farming. Results obtained using the bootstrap Data Envelopment Analysis methodology show that larger farms had lower yields and lower efficiency scores and more experienced farmers had higher efficiency scores. A Tobit analysis of the impact of environmental factors and subsidies on farm efficiency demonstrates that CAP subsidies cause perverse incentives, raising questions about the efficiency of such policies for sustainable agricultural development.

description: This paper introduces an alternative non-market value elicitation method—the “quasi-doublereferendum” (QDR)—applied to barrier island restoration in Mississippi. It is appropriate for surveys that elicit willingness-to-pay responses to multiple projects differing in scale only and can be used to increase efficiency while mitigating bias. We compare results to the more commonly used single-referendum (SR) method under two admissible ranges of willingness to pay: negative to positive infinity, and zero to income. The confidence intervals of the QDR models were narrower. We argue that the QDR approach should be less subject to bias than the commonly used double-referendum approach.

description: The present thesis is about creating an educational Web Application following the modern guidelines of the Responsive Web Design pattern. This pattern allows for an easier customisation of the functionality of the Application on demand, according to the user’s wishes and needs. Thus, it results on the optimisation of the user experience. The user experience therefore is unhindered by the type of device of the end user, or the size of the screen of the device in question. The creation of this Web Application also follows industry-standard methodology and utilises tools that are commonplace in the web development space nowadays.

description: The s-wave scattering length for elastic collisions between 87Rb atoms in the state |f,m_f>=|1,1> is measured in the vicinity of a Feshbach resonance near 1007 G. Experimentally, the scattering length is determined from the mean-field driven expansion of a Bose-Einstein condensate in a homogeneous magnetic field. The scattering length is measured as a function of the magnetic field and agrees with the theoretical expectation. The position and the width of the resonance are determined to be 1007.40 G and 0.20 G, respectively.

description: A series of carbon allotropes with novel optoelectronic and rich topological properties is predicted by systematic first-principles calculations. These fascinating carbon allotropes can be derived by inserting acetylenic linkages (-C$\equiv$C-) into graphite, hence they are termed as grapheaynes. Grapheaynes possess two different space groups, $P$2/$m$ or $C$2/$m$, and contain simultaneously the $sp$, $sp^2$, and $sp^3$ chemical bonds. They have formation energies lower than the already experimentally synthesized graphdiyne and other theoretically predicted carbon allotropes with acetylenic linkages. Particularly, when the width $n$ of grapheayne-$n$ exceeds 15, its cohesive energy is lower than that of diamond, and approaches that of graphite with increasing $n$. Remarkably, we find that some grapheaynes behave as semiconductors with direct narrow band gaps and own the highest absorption coefficients among all known semiconducting carbon allotropes, while some others are topological semimetals with nodal lines. Especially, some grapheaynes can be engineered with tunable direct band gaps in the range of 1.07-1.87 eV and have ideal properties for photovoltaic applications. Our work not only uncovers the unique atomic arrangement and prominent properties of the grapheayne family, but also offers a treasury that provides promising materials for catalyst, energy storage, molecular sieves, solar cell, and electronic devices.

description: Government programs that help agricultural producers manage risk may have environmental consequences. In recent years, premium subsidies for crop insurance have been increased substantially to encourage greater producer participation. Using detailed, producer-level crop insurance contract data in four regions, we investigate whether adverse environmental effects have resulted from these increased subsidies. We find some association between environmental effects and insurance contracts. On average, however, we find that environmental effects are generally small and as often beneficial as adverse. More importantly, we find that results are specific to local conditions and to particular environmental indicators and may be hidden in aggregate analysis.

description: Full-waveform inversion (FWI) is a widely used technique in seismic processing to produce high resolution Earth models that fully explain the recorded seismic data. FWI is a local optimisation problem which aims to minimise in a least-squares sense the misfit between recorded and modelled data. The inversion process begins with a best-guess initial model which is iteratively improved using a sequence of linearised local inversions to solve a fully non-linear problem. Deep learning has gained widespread popularity in the new millennium. At the core of these tools are Neural Networks (NN), in particular Deep Neural Networks (DNN) are variants of these original NN algorithms with significantly more hidden layers, resulting in efficient learning of a non-linear functional between input and output pairs. The learning process within DNN involves iteratively updating network neuron weights to best approximate input-to-output mappings. There is clearly similarity between FWI and DNN. Both approaches attempt to solve for a non-linear mapping in an iterative sense, however they are fundamentally different in that the former is knowledge-driven whereas the latter is data-driven. This article proposes a novel approach which learns pseudo-spectral data-driven FWI. We test this methodology by training a DNN on 1D multi-layer, horizontally-isotropic data and then apply this to previously unseen data to infer the surface velocity. Results are compared against a synthetic model and successfulness and failures of this approach are hence identified.

description: We present and analyse spectra of the Type IIn supernova 1994W obtained between 18 and 203 days after explosion. During the luminous phase (first 100 d) the line profiles are composed of three major components: (i) narrow P-Cygni lines with the absorption minima at -700 km/s; (ii) broad emission lines with BVZI ~4000 km/s; and (iii) broad, smooth wings, most apparent in H-alpha. These components are identified with an expanding circumstellar (CS) envelope, shocked cool gas in the forward post-shock region, and multiple Thomson scattering in the CS envelope, respectively. The absence of broad P-Cygni lines from the supernova is the result of the formation of an optically thick, cool, dense shell at the interface of the ejecta and the CS envelope. We model the supernova deceleration and Thomson scattering wings to recover the density, radial extent and Thomson optical depth of the CS envelope during the first month. We reproduce the light curve with a hydrodynamical model and find it to be powered by a combination of internal energy leakage after the explosion of an extended pre-supernova (~10^15 cm) and luminosity from circumstellar interaction. We recover the pre-explosion kinematics of the CS envelope: it is close to homologous expansion with outer velocity ~1100 km/s and a kinematic age of ~1.5 yr. The CS envelope's high mass and kinetic energy, combined with its small age, strongly suggest that the CS envelope was explosively ejected about 1.5 yr before the supernova explosion.

description: Because there are potential externality benefits, it is important to specify an appropriate statistical model when analyzing the conflict between agriculture and migratory waterfowl in Canada’s pothole region. Unlike non-spatial panel models, our use of a spatial autoregressive panel model identifies indirect impacts of agricultural activities on wetlands and waterfowl. In particular, we find that programs to restore wetlands in one location will result in enhanced duck productivity of wetlands and habitat in other locations within the study region. Even so, costs of protecting ducks could range from $107 to $204 per bird.

Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Modern applications are driving demand for ultra-reliable low-latency communications, rekindling interest in the performance of short, high-rate error correcting codes. To that end, here we introduce a soft-detection variant of Guessing Random Additive Noise Decoding (GRAND) called Ordered Reliability Bits GRAND that can decode any short, high-rate block-code. For a code of $n$ bits, it avails of no more than $\lceil\log_2(n)\rceil$ bits of code-book-independent quantized soft detection information per received bit to determine an accurate decoding while retaining the original algorithm's suitability for a highly parallelized implementation in hardware. ORBGRAND is shown to provide similar block error performance for codes of distinct classes (BCH, CA-Polar and RLC) with low complexity, while providing better block error rate performance than CA-SCL, a state of the art soft detection CA-Polar decoder.

description: In regulated industries, such as the water industry, it is of great significance to estimate productivity change as it helps policy makers to evaluate the effectiveness of regulatory regime and industry performance. In this paper, and for the first time, a translog input distance function was used to estimate and decompose productivity change into several components such as technical efficiency change, scale efficiency change, input-mix, and technical change. A further decomposition of technical change into neutral, output- and input-induced shifts of the frontier is provided. The above decomposition was applied to the English and Welsh water and sewerage companies and water only companies over the years 1993–2016. The results indicated that over the entire period water industry’s productivity increased by 9% per year, mainly due to scale efficiency change, input mix and technical change. On average water only companies reported higher productivity gains than water and sewerage companies.

description: We experimentally study the dynamics of quantum knots in a uniform magnetic field in spin-1 Bose-Einstein condensates. The knot is created in the polar magnetic phase, which rapidly undergoes a transition towards the ferromagnetic phase in the presence of the knot. The magnetic order becomes scrambled as the system evolves, and the knot disappears. Strikingly, over long evolution times, the knot decays into a polar-core spin vortex, which is a member of a class of singular SO(3) vortices. The polar-core spin vortex is stable with an observed lifetime comparable to that of the condensate itself. The structure is similar to that predicted to appear in the evolution of an isolated monopole defect, suggesting a possible universality in the observed topological transition.

description: Nonpoint-source pollution remains a troubling source of water quality problems despite decades of economics research on the matter. Among the chief difficulties for addressing the issue are the property rights assignments implicit in the current policy environment that favor agricultural nonpoint-source pollution, the unobservability of field-level emissions, and complex fate and transport relationships linking them to ambient water quality. Theoretical and practical considerations lead to the focus on observable abatement actions (conservation practices). Biophysical models are increasingly more capable of linking abatement actions to policy-relevant water quality outcomes. If costs of abatement actions are known, finding the least-cost mix of abatement actions is possible, while incorporating the nonlinearity of the pollution process. When costs are not known or information is incomplete, regulators can rely on flexible incentive-based programs, but the design of such programs is complicated by the complexities of emission aggregation. In this work, we focus on the regulator capable of focusing on nonpoint-source emitters. We address the design and performance of three practice-based approaches, ranging from the command-and-control approach mandating practices, to the more flexible performance standard approach where farmers are free to select the optimal mix of on-farm conservation practices, to a fully flexible approach where credits for conservation practices are freely tradable. We do so by utilizing the representation of the nonlinear emission aggregation (fate and transport) process (the Soil and Water Assessment Tool model), and consider cases ranging from the regulator having perfect information on the costs of conservation practices to no information at all. We show how workable programs utilizing the biophysical models and simulation-optimization approaches can be designed, and assess their performance relative to the efficient case. We find that flexible programs perform well both in terms of cost and water quality goals attainment. In particular, a trading program designed around an approximation of the nonlinear pollution process performs well, relative to first-best under no information on the cost of conservation practices.

description: The theorems of Kozlov and Sullivan characterize Gibbs measures as measures with positive continuous specifications. More precisely, Kozlov showed that every positive continuous specification on symbolic configurations of the lattice is generated by a norm-summable interaction. Sullivan showed that every shift-invariant positive continuous specification is generated by a shift-invariant interaction satisfying the weaker condition of variation-summability. These results were proven in the 1970s. An open question since that time is whether Kozlov's theorem holds in the shift-invariant setting, equivalently whether Sullivan's conclusion can be improved from variation-summability to norm-summability. We show that the answer is no: there exist shift-invariant positive continuous specifications that are not generated by any shift-invariant norm-summable interaction. On the other hand, we give a complete proof of an extension, suggested by Kozlov, of Kozlov's theorem to a characterization of positive continuous specifications on configuration spaces with arbitrary hard constraints. We also present an extended version of Sullivan's theorem. Aside from simplifying some of the arguments in the original proof, our new version of Sullivan's theorem applies in various settings not covered by the original proof. In particular, it applies when the support of the specification is the hard-core shift or the two-dimensional $q$-coloring shift for $q\geq 6$.

description: Human heart is a complex system that can be studied using its electrical activity recorded as Electrocardiogram (ECG). Any variations or anomalies in the ECG can indicate abnormalities in the cardiac dynamics. In this work, we present a detailed analysis of ECG data using the framework of recurrence network (RN). We show how the measures of the recurrence networks constructed from ECG data sets, can quantify the complexity and variability underlying the data. Our study shows for the first time that the RN from ECG show the unique feature of bimodality in their degree distribution. We relate this to the complex dynamics underlying the cardiac system, with structures at two spatial scales. We also show that that there is relevant information to be extracted from the scaling of measures with recurrence threshold. Thus we observe two scaling regions in the link density for ECG data which is compared with scaling in RNs from standard chaotic and hyperchaotic systems and noise. While both bimodality and scaling are common features of RNs from all types of ECG data, we find disease specific variations in them can be quantified.

Two light sterile neutrinos that mix maximally with each other and moderately with three active neutrinos

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Since the 3+1 neutrino models with one light sterile neutrino turn out to be not very effective, at least two light sterile neutrinos may be needed to reconcile the solar and atmospheric neutrino experiments with the LSND result, {\it if} this is confirmed by the ongoing MiniBooNE experiment (and when the CPT invariance is assumed to hold for neutrino oscillations). We present an attractive 3+2 neutrino model, where two light sterile neutrinos mix maximally with each other, in analogy to the observed maximal mixing of muon and tauon active neutrinos. But, while the mixing of $ν_e$ and $(ν_μ-ν_τ)/\sqrt2 $ is observed as large (though not maximal), the mixing of $ν_e$ with the corresponding combination of two light sterile neutrinos is expected to be only moderate because of the reported smallness of LSND oscillation amplitude. The presented model turns out, however, not to be {\it more} effective in explaining the hypothetic LSND result than the simplest 3+1 neutrino model. On the other hand, in the considered 3+2 model, the deviations from conventional oscillations of three active neutrinos appear to be {\it minimal} within a larger class of 3+2 models.

To ascertain the reality of BC’s supply position, we model the physical characteristics of BC’s hydroelectric generating system introducing variable head heights for the two dominant power stations. Using historical inflow and reservoir level data, we apply our linear programming model to investigate whether BC is capable of meeting is self-sufficiency goals under various supply and demand scenarios.

description: Chronic tinnitus is a complex, multi-factorial symptom that requires careful assessment and management. Evidence-based therapeutic approaches involve audiological and psychological treatment components. However, not everyone benefits from treatment. The identification and characterisation of patient subgroups (or “phenotypes”) may provide clinically relevant information. Due to the large number of assessment tools, data-driven methods appear to be promising. The acceptance of these empirical results can be further strengthened by a comprehensive visualisation. In this study, we used cluster analysis to identify distinct tinnitus phenotypes based on self-report questionnaire data and implemented a visualisation tool to explore phenotype idiosyncrasies. 1228 patients with chronic tinnitus from the Charité Tinnitus Center in Berlin were included. At baseline, each participant completed 14 questionnaires measuring tinnitus distress, -loudness, frequency and location, depressivity, perceived stress, quality of life, physical and mental health, pain perception, somatic symptom expression and coping attitudes. Four distinct patient phenotypes emerged from clustering: avoidant group (56.8%), psychosomatic group (14.1%), somatic group (15.2%), and distress group (13.9%). Radial bar- and line charts allowed for visual inspection and juxtaposition of major phenotype characteristics. The phenotypes differed in terms of clinical information including psychological symptoms, quality of life, coping attitudes, stress, tinnitus-related distress and pain, as well as socio-demographics. Our findings suggest that identifiable patient subgroups and their visualisation may allow for stratified treatment strategies and research designs.

description: Agonoscelis puberula Stål, 1854a
 Distribution: United States: AZ (Thomas et al. 2003), CA (Ortega-León et al. 2006), CO (Ortega-León et al. 2006), MN (Koch et al. 2014, but see note below), NM (Thomas et al. 2003, Bundy 2012), OK (Kondratieff et al. 2005), TX (Thomas et al. 2003), UT (Ortega-León et al. 2006).
 Comments: This species was not known from the New World until Thomas et al. (2003) recorded it from Mexico, the southern United States, and several West Indies islands; hence, it was not included in the Froeschner (1988) catalog. Agonoscelis puberula is very similar in general appearance to several species in the genus Trichopepla. It can usually be recognized by the dark markings on the veins of the hemelytral membrane, which are usually lacking in Trichopepla. We have examined the specimen from Minnesota and it is this species, but it might be an incidental or adventitious record.

description: Episodic accretion plays an important role in the evolution of young stars. Although it has been under investigation for a long time, the origin of such episodic accretion events is not yet understood. We investigate the dust and gas emission of a sample of young outbursting sources in the infrared to get a better understanding of their properties and circumstellar material, and we use the results in a further work to model the objects. We used Herschel data, from our PI program of 12 objects and complemented with archival observations to obtain the spectral energy distributions (SEDs) and spectra of our targets. We report here the main characteristics of our sample, focussing on the SED properties and on the gas emission lines detected in the PACS and SPIRE spectra. The SEDs of our sample show the diversity of the outbursting sources, with several targets showing strong emission in the far-infrared from the embedded objects. Most of our targets reside in a complex environment, which we discuss in detail. We detected several atomic and molecular lines, in particular rotational CO emission from several transitions from J=38-37 to J=4-3. We constructed rotational diagrams for the CO lines, and derived in three domains of assumed local thermodynamic equilibrium (LTE) temperatures and column densities, ranging mainly between 0-100 K and 400-500K. We confirm correlation in our sample between intense CO $J=16-15$ emission and the column density of the warm domain of CO, N(warm). We notice a strong increase in luminosity of HH 381 IRS and a weaker increase for PP 13 S, which shows the beginning of an outburst.

description: Η φυσιολογία του στρες συνιστά σημαντικό παράγοντα στη παθογένεση ποικίλων διαταραχών ψυχικής υγείας, επιδρώντας αρνητικά στην ευεξία του ανθρώπου για το υπόλοιπο της ζωής του. Ως ουσιαστικό μέρος της αυτής της διεργασίας αναγνωρίζεται ήδη στη βιβλιογραφία ο Άξονας Υποθαλάμου-Υπόφυσης-Επινεφριδίων, ρυθμιστής της παραγωγής της κορτιζόλης που αποτελεί τη βασική ορμόνη του στρες. Παρότι αυτή η σχέση της κορτιζόλης με τις ψυχικές διαταραχές έχει πολλαπλώς μελετηθεί, ο ρόλος της α-αμυλάσης ως βιοδείκτη στις καταθλιπτικές διαταραχές παραμένει εν πολλοίς ανεξερεύνητος, και ιδίως στον παιδικό και εφηβικό πληθυσμό. Στη βιβλιογραφία αποτυπώνονται σχετικά, ποικίλα ερωτήματα αναφορικά με τον τρόπο με τον οποίο μεταβάλλεται στα διάφορα ερεθίσματα, πώς διακυμαίνεται στις διάφορες ηλικιακές ομάδες, και διερευνάται πιθανή χρήση της ακόμη και στο διαγνωστικό μονοπάτι των ψυχικών διαταραχών. Οι διαταραχές της ψυχικής υγείας επιφέρουν σημαντική νοσηρότητα και θνησιμότητα στα άτομα που διαγιγνώσκονται με αυτές. Ταυτόχρονα, οι μακροπρόθεσμες οικονομικές και κοινωνικές επιπτώσεις που γεννούν, τόσο άμεσα όσο και έμμεσα λόγω του αποκλεισμού και της άνισης μεταχείρισης, τις καθιστούν σημαντικό πρόβλημα Δημόσιας Υγείας. Ο σκοπός της παρούσας βιβλιογραφικής ανασκόπησης είναι να αναδειχθεί ο πολυδιάστατος ρόλος της α-αμυλάσης ως βιοδείκτη στις ψυχικές παθήσεις των παιδιών και των εφήβων με εστίαση στις καταθλιπτικές διαταραχές. Από την αναζήτηση της βιβλιογραφίας στην MEDLINE και την EMBASE αντλήθηκαν 253 μελέτες εκ των οποίων οι 10 παρουσιάζουν δεδομένα συσχέτισης της α-αμυλάσης με κάποια καταθλιπτική διαταραχή και κρίθηκαν ως επιλέξιμες. Ωστόσο, τα σύγχρονα ερευνητικά δεδομένα δεν επαρκούν για να αποσαφηνιστεί ο ρόλος της α-αμυλάσης στις καταθλιπτικές διαταραχές των παιδιών και των εφήβων. Σαφείς μεθοδολογικές διαφοροποιήσεις μεταξύ των μελετών γεννούν σημαντική ετερογένεια και ποικιλία στα αποτελέσματα. Νέες, υψηλής τεκμηρίωσης, πρωτογενείς έρευνες απαιτούνται για την ανάδειξη πιθανών βιοδεικτών στη διαγνωστική και θεραπευτική διαδικασία των καταθλιπτικών διαταραχών. Στην εξίσωση αναμένεται η συνεκτίμηση πληθώρας παραμέτρων, με αυτήν του φύλου να συνοδεύεται από επαρκή τεκμηρίωση.

description: We study a zero-range process with two species of interacting particles. We show that the steady state assumes a simple factorised form, provided the dynamics satisfy certain conditions, which we derive. The steady state exhibits a new mechanism of condensation transition wherein one species induces the condensation of the other. We study this mechanism for a specific choice of dynamics.

description: Halyomorpha Mayr, 1864
 Halyomorpha is an Old World genus, currently containing 37 species, primarily in the African, Oriental, and Southeast Asian regions. Several of the included species are probably synonyms of other species, and several others will probably be transferred to other related genera. There are no modern keys to all of the species; Linnavuori (1982) provided a key to some of the African species, and Ahmad & Zaidi (1989) provided a key to some of the Indo-Pakistan species.

description: Small Cell Lung Carcinoma (SCLC) is a highly aggressive neuroendocrine malignancy, representing about 15% of lung cancers, and is marked by rapid progression, early metastasis, and high mortality (1). Significant heterogeneity exists in SCLC, characterized by the existence of distinct molecular subtypes that are determined by the varying expression of transcription factors such as ASCL1, NEUROD1, and POU2F3, each linked to unique biological behaviors and therapeutic responses (2). Additionally, recent studies have found a connection between neuronal activity and the development of both primary and metastatic SCLC (3).

description: We analyse the dynamics of a one-dimensional vertical Fabry-Pérot cavity, where the upper mirror levitates due to intra-cavity radiation pressure force. A perturbative approach is used based around separation of timescales, which allows us to calculate the physical quantities of interest. Due to the dynamics of the cavity field, we find that the upper mirror's motion will always be unstable for levitation performed using only a single laser. Stability can be achieved for two lasers, where one provides the trapping potential and the other a damping effect, and we locate and characterise all parameter regimes where this can occur. Finally we analyse photothermal effects due to heating of the mirror substrate. We show that this can stabilise the system, even with only a single input laser, if it acts to increase the optical path length of the cavity. This work serves as a foundation for understanding how levitated optical cavity schemes can be used as stable metrological platforms.

description: Blanket dry cow therapy in dairy cows is used to treat and prevent new infections during the dry period, regardless of the infection and the risk status of the cows. In our study we optimized the costs of dry cow therapy based on the somatic cell score before dry-off using linear programming. Our results showed that selective dry cow therapy can reduce the use of antibiotics in large US dairy herds with feasible economic benefits, contributing to a more prudent antibiotic use. This supplemental file provides detailed information about our regression models.
