description: Market failure results in more human conversion of ecosystems for development and other uses than likely socially desirable. In response, many government agencies and nonprofits focus on conservation, often acquiring land rights to establish protected areas on which further conversion of ecosystems is precluded. The protected areas created vary greatly in size, even within a particular conservation program. Here we examine the costs that conservation organizations face when acquiring sites for protection and pay particular attention to the consequences of this variability in protected area size. We use as our case study parcels in Central and Southern Appalachian forest ecosystems that were protected through fee simple acquisition and using easements by The Nature Conservancy, a nonprofit land trust. We compare these sites to unprotected areas similar to the protected areas in terms of site characteristics as identified by post-hoc matching methods. When comparing average costs, we found parcels protected under by fee simple transactions cost less than matched unprotected parcels, and that average costs of protecting parcels using easements were lower still. We also found that acquisition costs of protected areas achieve economies of scale under fee simple transactions. However, these economies of scale were often weaker than those present when considering matched, unprotected parcels. Parcels protected by easements did not show economies of scale with area. We were able to identify a subset of transactions where the agreed price was reduced to reflect an explicit donative intent on the part of the seller. For this subset of transactions, we found that the presence of donative intent disrupted any kind of systematic relationship between lot size and acquisition costs for conservation. Our findings imply that to achieve cost effective conservation, conservation organizations will need to strategize with respect to parcel size and contract type. For example, when acquiring parcels under a fee simple transaction, economies of scale in acquisition costs provide an incentive for conservation organizations to favor larger parcels, reinforcing ecological arguments that favor protecting larger protected areas. Also, by quantifying the cost differential between fee simple and easement acquisitions, we provide a benchmark for evaluating how much greater the ecological benefits of fee simple acquisition would have to be to provide the most effective option for conservation.

description: A new flipped $SU(3)_C\otimes SU(4)_L\otimes U(1)_X$ model without exotic electric charges is proposed. All the quarks families are arranged in the same representation while leptons generations are in different representations leading to a tree level FCNC. Moreover, It is shown that the cancellation of the triangle chiral anomalies requires new additional leptons 10-plet and quadruplet. All fermions masses have been also discussed. Furthermore, using the most recent experimental data of the branching ratios of $μ\to ee\bar{e}$ and $μ\to eγ$ rare decay modes, stringent bounds on the heavy neutral bosons masses and the muon-electron mixing matrix element are obtained.

description: Oncoming exoplanet spectro-imagers like the Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will aim for a new class of exoplanets, including Earth-like planets evolving around M dwarfs i.e., as close as 0.02 with contrasts around 10e-8. This goal can be achieved using coronagraphs. Classical coronagraphs are not optimal, however: 1) they usually impose a planetary photon loss, which is particularly problematic when the instrument includes a high spectral-resolution spectrograph, 2) some aberrations such as the missing segments of the ELT are dynamic and not compatible with a static coronagraph design, 3) the coupling of the exoplanet light into a fiber for spectroscopy only requires the electric field to be controlled on a small target-dependent region of the detector.
Such instruments would benefit from an adaptive tool to modulate the wavefront in both amplitude and phase. We propose to combine in the pupil plane a deformable mirror (DM) to control the phase and a digital micro-mirror device (DMD) i.e., an array made of millions of micro-mirrors able to switch between two positions, to provide a binary amplitude control. If the DM is already well-known in the field in particular for adaptive optics applications, the DMD has so far not been fully considered. At IPAG, we have assembled a testbed called CIDRE (Coronagraphy for DiRect Imaging of Exoplanets) to develop, test, calibrate, and validate the combination of these two components with a Lyot coronagraph. Since mid-2022, the testbed is operational and has entered its scientific exploitation phase albeit without the Lyot coronagraph yet, to test dynamic amplitude apodization coronagraphs (so-called Shaped Pupils

description: The critical temperature and condensate fraction of a trapped interacting Bose gas are investigated when both atom-atom interaction and finite-size effects are taken into account. Canonical ensemble is used to obtain the equations on the condensate fraction for the trapped interacting Bose gas near and below the critical temperature. In our approaches corrections due to atom-atom interaction and finite-size effects are obtained simultaneously for the critical temperature and condensate fraction of the system. Analytical high-order correction to the condensate fraction is given in this work.

description: We present the results of a spectral analysis of a large sample of subdwarf B stars selected from follow-up observations of candidates from the Hamburg Quasar Survey. Fundamental parameters (effective temperature, gravity, and helium abundance) were determined by matching synthetic line profiles calculated from model atmospheres to all hydrogen and helium absorption lines present in the observed optical spectra. The derived helium abundances are compared with the atmospheric parameters to search forpossible trends. We discovered a correlation between the helium abundance and the effective temperature: the larger the temperature, the larger the photospheric helium content of sdB stars. Additionally, a separation into two sequences of sdB stars in the effective temperature - helium abundance plane is detected. We compared our analysis results with data from the literature. The stars from our sample are found to be somewhat more luminous. This can only partlybe explained by NLTE effects. Three apparently normal B stars were discovered, which could be massive stars far away from the galactic plane (7-19kpc). Radial velocities were measured for 23 stars from which we discovered a new radial velocity variable sdB star.

description: Many machine/deep learning artificial neural networks are trained to simply be interpolation functions that map input variables to output values interpolated from the training data in a linear/nonlinear fashion. Even when the input/output pairs of the training data are physically accurate (e.g. the results of an experiment or numerical simulation), interpolated quantities can deviate quite far from being physically accurate. Although one could project the output of a network into a physically feasible region, such a postprocess is not captured by the energy function minimized when training the network; thus, the final projected result could incorrectly deviate quite far from the training data. We propose folding any such projection or postprocess directly into the network so that the final result is correctly compared to the training data by the energy function. Although we propose a general approach, we illustrate its efficacy on a specific convolutional neural network that takes in human pose parameters (joint rotations) and outputs a prediction of vertex positions representing a triangulated cloth mesh. While the original network outputs vertex positions with erroneously high stretching and compression energies, the new network trained with our physics prior remedies these issues producing highly improved results.

description: The exceptionally low-symmetry crystal structures of the time-reversal symmetry breaking superconductors LaNiC$_2$ and LaNiGa$_2$ lead to an internally-antisymmetric non-unitary triplet (INT) state as the only possibility compatible with experiments. We argue that this state has a distinct signature: a double-peak structure in the Density of States (DOS) which resolves in the spin channel in a particular way. We construct a detailed model of LaNiGa$_2$ capturing its electronic band structure and magnetic properties ab initio. The pairing mechanism is described via a single adjustable parameter. The latter is fixed by the critical temperature $T_c$ allowing parameter-free predictions. We compute the electronic specific heat and find excellent agreement with experiment. The size of the ordered moment in the superconducting state is compatible with zero-field muon spin relaxation experiments and the predicted spin-resolved DOS suggests the spin-splitting is within the reach of present experimental technology.

description: We study antiferromagnetic two-leg spin-1/2 ladders with strong bond randomness, using the real space renormalization group method. We find the low-temperature spin susceptibility of the system follows non-universal power laws, and the ground state spin-spin correlation is short-ranged. Our results suggest that there is no phase transition when the bond randomness increases from zero; for strong enough randomness the system is in a Griffith region with divergent spin susceptibility and short-range spin-spin correlation.

description: We present experimental results on the displacement of a domain wall by injection of a dc current through the wall. The samples are 1 micron wide long stripes of a CoO/Co/Cu/NiFe classical spin valve structure. The stripes have been patterned by electron beam lithography. A neck has been defined at 1/3 of the total length of the stripe and is a pinning center for the domain walls, as shown by the steps of the giant magnetoresistance curves at intermediate levels (1/3 or 2/3) between the resistances corresponding to the parallel and antiparallel configurations. We show by electric transport measurements that, once a wall is trapped, it can be moved by injecting a dc current higher than a threshold current of the order of magnitude of 10^7 A/cm^2. We discuss the different possible origins of this effect, i.e. local magnetic field created by the current and/or spin transfer from spin polarized current.

description: LiV2O4, a frustrated mixed valent metal (d^1 d^2), is argued to undergo two spin-screening processes. The first quenches the effective spin to produce the spin 1/2 behavior seen below room temperature[1], while the second produces the heavy fermi liquid character seen at low temperatures[2]. We present here a preliminary discussion of a t-J model with strong Hund's coupling of the strongly correlated d-electrons. Valence fluctuations of the Hubbard operators (S = {1/2} 1) combined with the frustration of the underlying corner-shared tetrahedral vanadium lattice are the essential components of our model.

description: We propose a novel data-driven approach for analyzing synchrotron Laue X-ray microdiffraction scans based on machine learning algorithms. The basic architecture and major components of the method are formulated mathematically. We demonstrate it through typical examples including polycrystalline BaTiO$_3$, multiphase transforming alloys and finely twinned martensite. The computational pipeline is implemented for beamline 12.3.2 at the Advanced Light Source, Lawrence Berkeley National Lab. The conventional analytical pathway for X-ray diffraction scans is based on a slow pattern by pattern crystal indexing process. This work provides a new way for analyzing X-ray diffraction 2D patterns, independent of the indexing process, and motivates further studies of X-ray diffraction patterns from the machine learning prospective for the development of suitable feature extraction, clustering and labeling algorithms.

Our predictions for the differential branching ratio is in better agreement with the LHCb data. Also, we find that the hQCD prediction for $R_{K^*ϕ}$, the ratio of the branching fraction of $B \to K^* μ^+ μ^-$ to that of $B_s \to ϕμ^+ μ^-$ , is in excellent agreement with both the LHCb and CDF results in low $q^2$ range.

description: Hepatic steatosis (HS) development and its risk factors in testicular germ cell tumor (TGCT) survivors have not been investigated. The study was designed as a retrospective observational study. Patients with existing HS at diagnosis were excluded. Serial imaging was utilized to detect HS. A total of 106 TGCT survivors were included. HS developed in 57% (n = 61) during a median follow-up of 51.8 months (8.5–241.5); 77% (n = 47) of those had persistent HS. Patients who developed HS had a higher baseline body mass index (BMI) (median 26.5 vs. 23.6 kg/m2, p = 0.000). Higher baseline BMI [adjusted odds ratio (aOR): 1.35, (95% CI: 1.10–1.65) p = 0.004] and S0 stage [aOR: 3.87, (95% CI: 1.18–12.67), p = 0.025] were associated with a higher risk of HS development. The median time from the diagnosis of TGCT to the detection of HS was 44.7 months (29.5–59.8). Higher baseline BMI was associated with earlier development of HS both in all patients [hazard ratio (HR): 1.16, (95% CI: 1.04–1.30), p = 0.007] and patients treated with the BEP regimen [HR: 1.21, (95% CI: 1.01–1.47), p = 0.038]. HS may be considered a long-term complication in TGCT patients. The risk is associated with baseline BMI. Diagnosis and management of HS should be implemented in the survivorship care plan of TGCT survivors.

description: Public health within the United States is becoming a concern not only from the perspective of rapidly expanding health care costs but also in terms of economic productivity. Obesity and other diet-related diseases are said to becoming epidemic. At the same time, in both rural and poorer urban areas, the notion of “food deserts”—geographic areas with limited access to and availability of affordable healthy foods—is gathering significant attention. While the complex relationships between poverty and health outcomes are well-documented, it is not clear if food access changes these relationships, especially in the rural United States.

In the case of the supernovae of AD 1604 and 1572 it is European records that provide the most accurate information available, whereas for earlier supernovae records are principally from East Asian sources. Also discussed briefly are several spurious supernova candidates, and the future prospects for studies of historical supernovae.

Bulk scattering is non trivial, provided that the bulk scattering matrix depends separately on the spectral parameters of the colliding particles, and not only on their difference. We show that a specific extension of a boundary algebra encodes the underlying scattering theory. The total scattering operator is constructed in this framework and shown to be unitary.

By using the method of optimal fluctuation and treating the order parameter self-consistently we show that the density of states is finite everywhere in the superconducting gap, and that it varies as $\ln N(E)\propto -|E-Δ_0|^{(7-d)/4}$ near the mean field gap edge $Δ_0$ in a d-dimensional superconductor. In contrast to most studied cases the optimal fluctuation is strongly anisotropic.

description: We investigate a corner of the Bianchi models that has not received much attention: "extended FLRW models" (eFLRW) defined as a cosmological model with underlying anisotropic Bianchi geometry that nevertheless expands isotropically and can be mapped onto a reference FLRW model with the same expansion history. In order to investigate the stability and naturalness of such models in a dynamical systems context, we consider spatially homogeneous models that contain a massless scalar field $φ$ and a non-tilted perfect fluid obeying an equation of state $p=wρ$. Remarkably, we find that matter anisotropies and geometrical anisotropies tend to cancel out dynamically. Hence, the expansion is asymptotically isotropic under rather general conditions. Although extended FLRW models require a special matter sector with anisotropies that are 'fine-tuned" relative to geometrical anisotropies, our analysis shows that such solutions are dynamically preferred attractors in general relativity. Specifically, we prove that all locally rotationally symmetric Bianchi type III universes with space-like $\nabla_μφ$ are asymptotically shear-free, for all $w\in[-1,1]$. Moreover, all shear-free equilibrium sets with anisotropic spatial curvature are proved to be stable with respect to all homogeneous perturbations for $w\geq -1/3$.

description: This case study analyses and compares the perceptions of agents that participate in different productive and commercial processes of the fishing activity (such as small-scale fisheries, distant-water fisheries and processing and commercialisation companies). It focuses on the regional level (Galicia, NW Spain) and considers sustainability, governance and socioeconomic aspects from the perspective of socioecological systems. Results show similarities and differences in agents’ perceptions related with specific aspects and problems relevant to each group, intersectoral relations and sustainability issues. In this sense, agents share a positive perception of the sustainability objectives proposed by international organisations, as well as concerns about the uncertainty linked to globalisation processes. However, they differ in their evaluation of some specific regulatory measures. Regulatory policies could consider this information in order to achieve a greater degree of complicity and compliance by fishers and other agents of the value chain.

description: Several easy to understand and computationally tractable imprecise probability models, like the Pari-Mutuel model, are derived from a given probability measure P_0. In this paper we investigate a family of such models, called Nearly-Linear (NL). They generalise a number of well-known models, while preserving a simple mathematical structure. In fact, they are linear affine transformations of P_0 as long as the transformation returns a value in [0,1] . We study the properties of NL measures that are (at least) capacities, and show that they can be partitioned into three major subfamilies. We investigate their consistency, which ranges from 2-coherence, the minimal condition satisfied by all, to coherence, and the kind of beliefs they can represent. There is a variety of different situations that NL models can incorporate, from generalisations of the Pari-Mutuel model, the ε-contamination model and other models to conflicting attitudes of an agent towards low/high P_0-probability events (both prudential and imprudent at the same time), or to symmetry judgments. The consistency properties vary with the beliefs represented, but not strictly: some conflicting and partly irrational moods may be compatible with coherence. In a final part, we compare NL models with their closest, but only partly overlapping, models, neo-additive capacities and probability intervals.

description: The financing of agricultural research presents a unique policy problem. While research is often funded by national or subnational governments, the benefits of research often spill across the boundaries of the government financing the research. Many observers of international agricultural research have noted that the spillover problem exists and that policy changes are needed if an internationally optimal level of investment in research is to be provided (Judd, et al., 1987; Idachaba, 1981; Ruttan, 1987b). Some empirical studies have attempted to measure international benefit spillovers (Evenson, 1977; Davis, et al., 1987; Edwards and Freebairn 1984), and others have attempted to establish criteria for allocating research resources (ldachaba, 1989, p. 6; Paz, 1981; Norton and Pardey, 1987; Fishel, 1971; de Castro and Schuh, 1977; Carter, 1985). None of these studies has addressed two central policy questions: what policy tools are available for achieving an optimal level of investment in research and what institutional innovations are required to make these policy tools operable? This paper uses public finance theory to address these questions. First, the sources of international benefit spillovers will be examined. Second, public finance theory will be used to examine the policy tools available for achieving institutional coordination in financing research. Third, empirical estimates of international benefit spillovers will be reviewed. Finally, the policy implications of this research will be examined, with special emphasis on the institutional innovations needed to finance an optimal level of agricultural research.
Tail Dependence of Factor Models

description: Using the framework of factor models, we establish the general expression of the coefficient of tail dependence between the market and a stock (i.e., the probability that the stock incurs a large loss, assuming that the market has also undergone a large loss) as a function of the parameters of the underlying factor model and of the tail parameters of the distributions of the factor and of the idiosyncratic noise of each stock. Our formula holds for arbitrary marginal distributions and in addition does not require any parameterization of the multivariate distributions of the market and stocks. The determination of the extreme parameter, which is not accessible by a direct statistical inference, is made possible by the measurement of parameters whose estimation involves a significant part of the data with sufficient statistics. Our empirical tests find a good agreement between the calibration of the tail dependence coefficient and the realized large losses over the period from 1962 to 2000. Nevertheless, a bias is detected which suggests the presence of an outlier in the form of the crash of October 1987.

The economics of waste oil recycling in the EU

description: In 2018, 1.6 million tonnes of waste oil were collected in the European Union. About 61% of the waste oil was regenerated – i.e. it was turned into base oil again – and 39% followed energy recovery pathways either in the form of conversion to fuel or via direct incineration. Although the life-cycle literature largely agrees that regeneration outperforms energy recovery in the EU in terms of greenhouse gas emissions and societal costs, policies to boost regeneration and their socio-economic impacts remain underexplored. We fill this gap by discussing policies for managing waste oil flows and by systematically assessing their socio-economic impacts. We analyse different policies that would induce an increase in the regeneration rate of waste oil from the current 61% to either 70% or 85% and assess how the type and magnitude of impacts as well as their distribution across different actors varies, depending on the policy design. The policies lead to a net saving in terms of avoided societal costs and to moderate gains in employment. However, when accounting for estimated administrative costs, these benefits are likely insufficient to justify regulatory intervention.

description: The task of learning a sentiment classification model that adapts well to any target domain, different from the source domain, is a challenging problem. Majority of the existing approaches focus on learning a common representation by leveraging both source and target data during training. In this paper, we introduce a two-stage training procedure that leverages weakly supervised datasets for developing simple lift-and-shift-based predictive models without being exposed to the target domain during the training phase. Experimental results show that transfer with weak supervision from a source domain to various target domains provides performance very close to that obtained via supervised training on the target domain itself.

description: We present time-series spectroscopy and multi-band photometry of the sdBV PG 1605+072 carried out simultaneously at the Calar Alto 2.2m and 3.5m telescopes. The periodogram analysis of the radial velocity curves reveals three frequencies at 2.078, 2.756, and 1.985 mHz for Hbeta and at 2.076, 2.753, and 1.978 mHz for Hgamma. The corresponding radial velocity amplitudes are 12.7, 8.0, and 7.9 km/s for Hbeta and 14.3, 6.5, and 7.2 km/s for Hgamma. Furthermore, we found five frequencies that are present in all wavelength bands of the BUSCA photometer. The frequencies detected in the radial velocity curves are recovered by the photometric measurements. Moreover, additional frequencies were present in the periodograms which could not be identified in all four bands simultaneously. The comparison of the amplitudes presented here with previous results from radial velocity and photometric observations of PG 1605+072 shows a significant change or even switch in the power of the modes within short time scales, i. e. about one year. No changes in frequency were registered and the phases of the modes show no wavelength dependency within our multi-band photometry.

description: At DTU Wind Energy, a 12.6 m reference wind turbine rotor blade and the
corresponding blade moulds were designed and manufactured. The entire blade design and the related test data will be published according to the FAIR principles. The blade moulds are intended to serve as a blade research and demonstration platform, allowing to realise theoretical concepts and testing these in full-scale on a wind turbine blade and thus enabling a comparison to numerical solutions. In this article, the preliminary blade design progress and process, initial load calculations and a 3D scan of the blade molds are presented.
Double inclusive small-x gluon production and their azimuthal correlations in a biased ensemble

description: We consider double $gg\rightarrow g$ production in the presence of a bias on the unintegrated gluon distribution of the colliding hadron or nuclei. Such bias could be due to the selection of configurations with a greater number of gluons or higher mean transverse momentum squared or, more generally, due to a modified spectral shape of the gluon distribution in the hadrons. Hence, we consider reweighted functional averages over the stochastic ensemble of small-x gluons. We evaluate explicitly the double inclusive gluon transverse momentum spectrum in high-energy collisions, and their azimuthal correlations, for a few simple examples of biases.
description: 15 pages. Resubmitted 2/20/20, in line with referee comments for upcoming publication to Physics Review D. A paragraph was added at the beginning of the introduction, so to begin the paper with a broader presentation of using biased ensembles to better understand various observables in particle collisions

description: The recognition of Ignorance and its sociological attachments regarding its close proximity to Early Islamic Community is very important. Moreover the essence and the features of Ignorance indicate not only be considered to the pre-Islamic period but also on the contrary to Islam and any fundamental transition, one of the initial steps studying the ratio of a society to the Ignorance is, the perception of its meanings, concepts and subjects. Among the existing in this arena, beside the Holy Qur’an and The Hadiths of Prophet (PBUH), the sermons of Ali (PBUH) is of considerable importance. Applying descriptive approach by using the grounded theory method, through the constancy between the inductive reasoning (creating concepts, subjects and the relations in between) and deductive reasoning (examining the concepts, subjects and the relations in between). This research intends to find the dominant criteria in evaluating the ratio of society to Ignorance in Nahdj al-Balagha and renders the term “irrational-faith” as the major concept in this arena.
