description: Aims: AT 2018hso is a new transient showing transitional properties between those of LRNe and the class of intermediate luminosity red transients (ILRTs) similar to SN 2008S. Through the detailed analysis of the observed parameters, our study support that it actually belongs to the LRN class, and was likely produced by the coalescence of two massive stars. Methods: We obtained ten months of optical and near-infrared photometric monitoring, and eleven epochs of low-resolution optical spectroscopy of AT~2018hso. We compared its observed properties with those of other ILRTs and LRNe. We also inspected the archival Hubble Space Telescope (HST) images obtained about 15 years ago to constrain the progenitor's properties. Results: The light curves of AT 2018hso show a first sharp peak (Mr = -13.93 mag), followed by a broader and shallower second peak, that resembles a plateau in the optical bands. The spectra dramatically change with time. Early time spectra show prominent Balmer emission lines and a weak Ca II] doublet, which is usually observed in ILRTs. However, the major decrease in the continuum temperature, the appearance of narrow metal absorption lines, the major change in the H$α$ strength and profile, and the emergence of molecular bands support a LRN classification. The possible detection of an I ~ -8 mag source at the position of AT 2018hso in HST archive images is consistent with expectations for a pre-merger massive binary, similar to the precursor of the 2015 LRN in M101. Conclusions: We provide reasonable arguments to support a LRN classification for AT~2018hso. This study reveals growing heterogeneity in the observables of LRNe than thought in the past, making sometimes tricky the discrimination between LRNe and ILRTs. This suggests the need of monitoring the entire evolution of gap transients to avoid misclassifications.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Abstract: Background: Behr syndrome is a clinically distinct, but genetically heterogeneous disorder characterized by optic atrophy, progressive spastic paraparesis, and motor neuropathy often associated with ataxia. The molecular diagnosis is based on gene panel testing or whole-exome/genome sequencing. Methods: Here, we report the clinical presentation of two siblings with a novel genetic form of Behr syndrome. We performed whole-exome sequencing in the two patients and their mother. Results: Both patients had a childhood-onset, slowly progressive disease resembling Behr syndrome, starting with visual impairment, followed by progressive spasticity, weakness, and atrophy of the lower legs and ataxia. They also developed scoliosis, leading to respiratory problems. In their late 30’s, both siblings developed a hypertrophic cardiomyopathy and died of sudden cardiac death at age 43 and 40, respectively. Whole-exome sequencing identified the novel homozygous c.627_629del; p.(Gly210del) deletion in UCHL1. Conclusions: The presentation of our patients raises the possibility that hypertrophic cardiomyopathy may be an additional feature of the clinical syndrome associated with UCHL1 mutations, and highlights the importance of cardiac follow-up and treatment in neurodegenerative disease associated with UCHL1 mutations.

description: Tourism is an essential industry promoting economic development of Nyingchi and also plays a great role in national economy. Increasing people’s income and improving living conditions are starting points of promoting tourism development. This survey indicates that tourism in Nyingchi develops rapidly, growth rate of tourists is slightly lower than growth rate of income, and per capita tourist consumption is also increasing. Comparative analysis indicates that tourist resources, traffic condition, tourism propaganda intensity, development intensity of relevant products, and seasonal factor have significant influence on ensuring supply and increasing income of farmers. Further analysis shows that low educational level, weak basic tourism knowledge, backward tourism sanitation, and lagging tourist service infrastructure are major problems and obstacles. Resource advantages of scenic spots, setting foot on structural adjustment of characteristic industry, developing specialized farmer cooperatives and leading enterprises, and deeply exploring intension of tourist culture are major approaches for ensuring supply and increasing income of farmers. In sum, it is urgent and important to strengthen ability of ensuring supply and increasing income in improving people’s living conditions and promoting tourism development.

description: Based on information entropy theory and ecological footprint theory, we analyze the changes in land use and land ecological carrying capacity in Huangguoshu scenic area during 2009-2012. The results show that the area of arable land and construction land was relatively increased while the area of grassland and woodland was relatively reduced in Huangguoshu scenic area during 2009-2012, and the information entropy showed a wavy change. It indicates that the land use in the study area poses increasing pressure on the ecological environment, and there is a need to strengthen ecological protection and achieve the coordinated development of land use and ecological environment construction.

description: We investigate the stability of katabatic slope flows over an infinitely wide and uniformly cooled planar surface subject to an additional forcing due to a uniform downslope wind field aloft. We adopt an extension of Prandtl's original model for slope flows (Lykosov & Gutman 1972) to derive the base flow, which constitutes an interesting basic state in stability analysis because it cannot be reduced to a single universal form independent of external parameters. We apply a linear modal analysis to this basic state to demonstrate that for a fixed Prandtl number and slope angle, two independent dimensionless parameters are sufficient to describe the flow stability. One of these parameters is the stratification perturbation number that we have introduced in Xiao & Senocak (2019). The second parameter, which we will henceforth designate the wind forcing number, is hitherto uncharted and can be interpreted as the ratio of the kinetic energy of the ambient wind aloft to the damping due to viscosity and stabilizing effect of the background stratification. For a fixed Prandtl number, stationary transverse and travelling longitudinal modes of instabilities can emerge, depending on the value of the slope angle and the aforementioned dimensionless numbers. The influence of ambient wind forcing on the base flow's stability is complicated as the ambient wind can be both stabilizing as well as destabilizing for a certain range of the parameters. Our results constitute a strong counter-evidence against the current practice of relying solely on the gradient Richardson number to describe the dynamic stability of stratified atmospheric slope flows.

description: Recent PHENIX Au+Au -> e- + X data from open charm decay are shown to be consistent with two extreme opposite dynamical scenarios of ultra-relativistic nuclear reactions. Perturbative QCD without final state interactions was previously shown to be consistent with the data. However, we show that the data are also consistent with zero mean free path hydrodynamics characterized by a common transverse flow velocity field. The surprising coincidence of both D and B hydrodynamic flow spectra with pQCD up to p_T ~ 3 and 5 GeV, respectively, suggests that heavy quarks may be produced essentially at rest in the rapidly expanding gluon plasma. Possible implications and further tests of collective heavy quark dynamics are discussed.

description: Using MOD10A1, temperature and precipitation of 21 meteorological observatories and HJ-1/CCD data from July to September during 2002—2013, this paper takes the Tianshan Mountains as the study area to analyze the space distribution characteristics of snow line and its influencing factors. The results show that the snowline distribution of southern and northern slopes of the Tianshan Mountains is that it is high in the south and east but low in north and west; the snowline of southern slope is sparse and there is a small spatial gradient change; the snow line is dense in the middle of northern slope, and the spatial gradient change is not large. Through the analysis of the whole study area, it is found that the correlation coefficient between snow line altitude and temperature is 0.159, and the partial correlation coefficient between them is -0.212; the correlation coefficient between snow line altitude and precipitation is -0.668, and the partial correlation coefficient between them is -0.676. Precipitation is the dominant factor that affects the distribution of snow line of southern and northern slopes of the Tianshan Mountains.

description: The EU H2020 BIORIMA project is one of the first and largest European initiatives that
 is totally dedicated to the development of innovative and robust methodologies to
 assess and manage the risks of nano-biomaterials (NBM) that are used in medical
 devices and advanced medicinal therapy products, along their whole life cycle, and at
 the same time identify and implement suitable safety-by-design alternatives. The
 BIORIMA consortium is implementing a comprehensive method testing and validation
 program to adapt and further develop existing tools for human and environmental
 exposure and hazard assessment of NBM, beyond clinical studies. All approaches that
 are tested and developed are integrated into a risk management framework (RMF) to
 help practitioners and end-users in finding best practical solutions for testing and
 handling of NBM. The RMF will be implemented by means of a web-based and
 specially designed Decision Support System (DSS), to comply with existing relevant
 regulations, such as MDR 2017/745 or REACH. The poster describes the latest
 findings of the project after 3 years of intensive research on the hazard of NBM and of
 the underlying mechanisms that are crucial for the effects and exposure we observe in
 humans and the environment.

description: Abstract: Background: Unicellular species make up the majority of eukaryotic diversity, however most studies on transposable elements (TEs) have centred on multicellular host species. Such studies may have therefore provided a limited picture of how transposable elements evolve across eukaryotes. The choanoflagellates, as the sister group to Metazoa, are an important study group for investigating unicellular to multicellular transitions. A previous survey of the choanoflagellate Monosiga brevicollis revealed the presence of only three families of LTR retrotransposons, all of which appeared to be active. Salpingoeca rosetta is the second choanoflagellate to have its whole genome sequenced and provides further insight into the evolution and population biology of transposable elements in the closest relative of metazoans. Results: Screening the genome revealed the presence of a minimum of 20 TE families. Seven of the annotated families are DNA transposons and the remaining 13 families are LTR retrotransposons. Evidence for two putative non-LTR retrotransposons was also uncovered, but full-length sequences could not be determined. Superfamily phylogenetic trees indicate that vertical inheritance and, in the case of one family, horizontal transfer have been involved in the evolution of the choanoflagellates TEs. Phylogenetic analyses of individual families highlight recent element activity in the genome, however six families did not show evidence of current transposition. The majority of families possess young insertions and the expression levels of TE genes vary by four orders of magnitude across families. In contrast to previous studies on TEs, the families present in S. rosetta show the signature of selection on codon usage, with families favouring codons that are adapted to the host translational machinery. Selection is stronger in LTR retrotransposons than DNA transposons, with highly expressed families showing stronger codon usage bias. Mutation pressure towards guanosine and cytosine also appears to contribute to TE codon usage. Conclusions: S. rosetta increases the known diversity of choanoflagellate TEs and the complement further highlights the role of horizontal gene transfer from prey species in choanoflagellate genome evolution. Unlike previously studied TEs, the S. rosetta families show evidence for selection on their codon usage, which is shown to act via translational efficiency and translational accuracy.

description: For a two-qubit state the isotropic strength measures the degree of isotropic spin correlation. The concept of isotropic strength is generalized to multipartite qudit systems, and the strength distributions for tripartite and quadripartite qudit systems are thoroughly investigated. We show that the sum of relative isotropic strengths of any three qudit state over $d$-dimensional Hilbert space cannot exceed $d-1$, which generalizes of the case $d=2$. The trade-off relations and monogamy-like relations of the sum of spin correlation strengths for pure three- and four-partite systems are derived. Moreover, the bounds of spin correlation strengths among different subsystems of a quadripartite state are used to analyze quantum entanglement.

description: We show that molecular dynamics simulations can furnish useful boundary conditions at a solid surface bounding a two-component fluid. In contrast to some previous reports, convective-diffusive flow is consistent with continuum equations down to atomic scales. However, concentration gradients can produce flow without viscous dissipation that is inconsistent with the commonly used Navier slip condition. Also, differential wetting of the two components coupled to a concentration gradient can drive convective flows that could be used to make nano-pumps or motors.

description: Neutrino oscillations are precision probes of new physics beyond the Standard Model. Apart from neutrino masses and mixings, they are also sensitive to possible deviations of low-energy interactions between quarks and leptons from the Standard Model predictions. In this paper we develop a systematic description of such non-standard interactions (NSI) in oscillation experiments within the quantum field theory framework. We calculate the event rate and oscillation probability in the presence of general NSI, starting from the effective field theory (EFT) in which new physics modifies the flavor or Lorentz structure of charged-current interactions between leptons and quarks. We also provide the matching between the EFT Wilson coefficients and the widely used simplified quantum-mechanical approach, where new physics is encoded in a set of production and detection NSI parameters. Finally, we discuss the consistency conditions for the standard NSI approach to correctly reproduce the quantum field theory result.

description: The literature dealing with impacts of Bt cotton is growing. Nevertheless, the question remains about how this technology can contribute to employment generation of rural poor. Bt-related yield benefit may intensify production and enhance labor demand for harvesting. Building on farm survey data of 352 cotton farmers in the South Punjab of Pakistan and using double-hurdle model, Bt employments effects are analyzed. Estimates show that Bt adoption has increased the probability and demand for hired labor by 6% and 17%, respectively. Cotton picking is labor intensive and female dominated activity in Pakistan. Labor disaggregation by gender enunciates the employment effects of Bt cotton for rural women, who belong to the neglected group of the society. Hence, Bt technology can play a vital role to poverty alleviation if seed quality and credit constraints are properly addressed.

description: We discuss symmetry fractionalization of the Lorentz group in (2+1)$d$ non-spin quantum field theory (QFT), and its implications for dualities. We prove that two inequivalent non-spin QFTs are dual as spin QFTs if and only if they are related by a Lorentz symmetry fractionalization with respect to an anomalous $\mathbb{Z}_2$ one-form symmetry. Moreover, if the framing anomalies of two non-spin QFTs differ by a multiple of 8, then they are dual as spin QFTs if and only if they are also dual as non-spin QFTs. Applications to summing over the spin structures, time-reversal symmetry, and level/rank dualities are explored. The Lorentz symmetry fractionalization naturally arises in Chern-Simons matter dualities that obey certain spin/charge relations, and is instrumental for the dualities to hold when viewed as non-spin theories.

description: To account for the effects of heterogeneity in micro-econometric models has been major concern in labor economics, empirical industrial organization or trade economics for at least two decades. The micro-econometric agricultural production choice models found in the literature largely ignore the impacts of unobserved heterogeneity. This can partly be explained by the dimension of these models which deals with a large set of choices, e.g., acreage choices, input demands and yield supplies. We propose a random parameter framework to account for the unobserved heterogeneity in micro-econometric agricultural production choices models. This approach allows accounting for unobserved farms’ and farmers’ heterogeneity in a fairly flexible way. We estimate a system of yield supply and acreage choice equations with a panel set of French crop growers. Our results show that heterogeneity significantly matters in our empirical application and that ignoring the heterogeneity of farmers’ choice processes can have important impacts on simulation outcomes. Due to the dimension of the estimation problem and the functional form of the considered production choice model, the Simulated Maximum Likelihood approach usually considered in the applied econometrics literature in such context is empirically intractable. We show that specific versions of the Stochastic Expectation-Maximization algorithms proposed in the statistics literature are easily implemented for estimating random parameter agricultural production models.

description: We present a comprehensive spectroscopic study of the integrated light of metal-rich Galactic globular clusters and the stellar population in the Galactic bulge. We measure line indices which are defined by the Lick standard system and compare index strengths of the clusters and Galactic bulge. Both metal-rich globular clusters and the bulge are similar in most of the indices, except for the CN index. We find a significant enhancement in the CN/ index ratio in metal-rich globular clusters compared with the Galactic bulge. The mean iron index of the two metal-rich globular clusters NGC 6528 and NGC 6553 is comparable with the mean iron index of the bulge. Index ratios such as Mgb/, Mg2/, Ca4227/, and TiO/, are comparable in both stellar population indicating similar enhancements in individual elements which are traced by the indices. From the globular cluster data we fully empirically calibrate several metallicity-sensitive indices as a function of [Fe/H] and find tightest correlations for the Mg2 index and the composite [MgFe] index. We find that all indices show a similar behavior with galactocentric radius, except for the Balmer series, which show a large scatter at all radii. However, the scatter is entirely consistent with the cluster-to-cluster variations in the horizontal branch morphology.

description: We have directly observed self-trapped electrons and holes in PbBr$_{2}$ crystals with electron-spin-resonance (ESR) technique. The self-trapped states are induced below 8 K by two-photon interband excitation with pulsed 120-fs-width laser light at 3.10 eV. Spin-Hamiltonian analyses of the ESR signals have revealed that the self-trapping electron centers are the dimer molecules of Pb$_2$$^{3+}$ along the crystallographic a axis and the self-trapping hole centers are those of Br$_2$$^-$ with two possible configurations in the unit cell of the crystal. Thermal stability of the self-trapped electrons and holes suggests that both of them are related to the blue-green luminescence band at 2.55 eV coming from recombination of spatially separated electron-hole pairs.

description: In this paper, the authors analyze the linkage between and the determinants of organic fertilizer and modern varieties (MVs) adoptions in Burkina Faso. Using simultaneous recursive and endogenous switching probit models, we found a positive joint determination along with a negative endogeneity between the two technologies, indicating controlling for observable variables adoption decisions of the two technologies are positively correlated, but unobserved factors that affect one decision are negatively correlated with the other, or vice versa. After controlling for jointness and endogeneity, we found a significant positive effect of organic fertilizer application on MVs adoption. But, the two technologies are reversely affected by household head’s attending formal education and the incidence of soil fertility problem within the farm. The size of good land holding appears to have a positive effect on both adoption decisions. Other factors that significantly affect MVs adoption with positive effect are number of cashcrop grown and remittances. The study suggests that organic fertilizer can serve as enabling factor for greater adoption of MVs, especially in less favourable climate areas. In areas where farmers invest less in inorganic fertilizer because of higher climate and market risks, organic fertilizer can serve as an effective alternative to replace inorganic fertilizer in the adoption process of MVs. Policies to promote green revolution technologies in Sub-Saharan Africa could be more effective if jointly associated with the promotion of conservation agriculture technologies.
title: Final Environmental Assessment, Regulatory Impact Review, and Final Regulatory Flexibility Analysis for the Rule to Prohibit the Commercial and Recreational Retention of Oceanic Whitetip Sharks in U.S. Atlantic Waters and Hammerhead Sharks in the U.S. Caribbean Sea

description: On May 15, 2020, NOAA Fisheries issued two Biological Opinions (BiOps) for Atlantic highly migratory species (HMS): one for the pelagic longline (PLL) fishery and one for the non-PLL fisheries. As a result of the Endangered Species Act (ESA) listing for oceanic whitetip sharks and the Central and Southwest Atlantic Distinct Population Segment (DPS) of scalloped hammerhead sharks, the BiOps strongly encouraged the inclusion of these federally protected species on the HMS list of prohibited shark species for recreational and/or commercial HMS fisheries. Under existing regulations, retention and possession of oceanic whitetip sharks and all hammerhead sharks are prohibited for commercial fishermen using PLL gear and recreational fishermen who have tunas, swordfish, and/or billfish on board. For oceanic whitetip sharks, this action would extend the prohibitions to all HMS permitted fishermen by adding oceanic whitetip sharks to the prohibited sharks species group using the criteria in 50 CFR § 635.34(c). Although only the scalloped hammerhead shark Central and Southwest Atlantic DPS is listed under the ESA, this action prohibits retention of great, smooth, and scalloped hammerhead sharks for all HMS permitted fishermen in the U.S. Caribbean region due to the likelihood of misidentification by fishermen. This action is being taken pursuant to the rulemaking authority under the Magnuson-Stevens Fishery Conservation and Management Act, section 304(g).

description: Gait event detection of the initial contact and toe off is essential for running gait analysis, allowing the derivation of parameters such as stance time. Heuristic-based methods exist to estimate these key gait events from tibial accelerometry. However, these methods are tailored to very specific acceleration profiles, which may offer complications when dealing with larger data sets and inherent biological variability. Therefore, this paper investigates whether a structured machine learning approach can achieve a more accurate prediction of running gait event timings from tibial accelerometry. Force-based event detection acted as the criterion measure in order to assess the accuracy, repeatability and sensitivity of the predicted gait events. A heuristic method and two structured machine learning methods were employed to derive initial contact, toe off and stance time from tibial acceleration signals. Both a structured perceptron model (median absolute error of stance time estimation: 10.00 $\pm$ 8.73 ms) and a structured recurrent neural network model (median absolute error of stance time estimation: 6.50 $\pm$ 5.74 ms) significantly outperformed the existing heuristic approach (median absolute error of stance time estimation: 11.25 $\pm$ 9.52 ms) on data from 93 rearfoot runners. Thus, results indicate that a structured recurrent neural network machine learning model offers the most accurate and consistent estimation of the gait events and its derived stance time during level overground running. The machine learning methods seem less affected by intra- and inter-subject variation within the data, allowing for accurate and efficient automated data output during rearfoot overground running. Furthermore offering possibilities for real-time monitoring and biofeedback during prolonged measurements, even outside the laboratory.

description: Molecular networks guide the biochemistry of a living cell on multiple levels: its metabolic and signalling pathways are shaped by the network of interacting proteins, whose production, in turn, is controlled by the genetic regulatory network. To address topological properties of these two networks we quantify correlations between connectivities of interacting nodes and compare them to a null model of a network, in which al links were randomly rewired. We find that for both interaction and regulatory networks, links between highly connected proteins are systematically suppressed, while those between a highly-connected and low-connected pairs of proteins are favored. This effect decreases the likelihood of cross talk between different functional modules of the cell, and increases the overall robustness of a network by localizing effects of deleterious perturbations.

description: The present study has analysed the trend in the total factor productivity (TFP) of major edible oilseeds in India during 1985-2010, and has decomposed the changes in TFP into its constituent components viz. technical change and efficiency change using Malmquist TFP approach. The study revealed that the productivity growth of groundnut, rapeseed/mustard and soybean has decelerated during period II (1996-2010) compared to period I (1985-1995). During the overall period TFP change was positive for groundnut and rapeseed/mustard, but negative for soybean. Period II has recorded increased TFP changes in two out of three states for groundnut and rapeseed/ mustard. For soybean, TFP change was positive in one out of three major state only. The entire change in TFP in case of all the crops was on account of technical change, with no contribution from changes in efficiency. The depressed productivity growth in many states despite positive TFP growth could be due to slowdown in input intensification. This situation warrants policy focus.

description: The dibaryon states as six-quark clusters of exotic QCD states are investigated in this paper. With the inherent nodal surface structure analysis, the wave functions of the six-quark clusters (in another word, the dibaryons) are classified. The contribution of the hidden color channels are discussed. The quantum numbers of the low-lying dibaryon states are obtained. The States $[ΩΩ]_{(0,0^{+})}$, $[ΩΩ]_{(0,2^{-})}$, $[Ξ^{*}Ω]_{(1/2,0^{+})}$, $[Σ^{*}Σ^{*}]_{(0,4^{-})}$ and the hidden color channel states with the same quantum numbers are proposed to be the candidates of dibaryons, which may be observed in experiments.

description: In previous work, Gardiner et al. (1999) found evidence for a discrepancy between the Teff obtained from Balmer lines with that from photometry and fundamental values for A-type stars. An investigation into this anomaly is presented using Balmer line profiles of stars in binary system with fundamental values of both Teff and log g. A revision of the fundamental parameters for binary systems given by Smalley & Dworetsky (1995) is also presented. The Teff obtained by fitting Halpha and Hbeta line profiles is compared to the fundamental values and those obtained from uvby photometry. We find that the discrepancy found by Gardiner et al. (1999) for stars in the range 7000 K < Teff < 9000 K is no longer evident.

description: We present the results of a study of specific heat on a single crystal of Pr$_{0.63}$Ca$_{0.37}$MnO$_3$ performed over a temperature range 3K-300K in presence of 0 and 8T magnetic fields. An estimate of the entropy and latent heat in a magnetic field at the first order charge ordering (CO) transition is presented. The total entropy change at the CO transition which is $\approx$ 1.8 J/mol K at 0T, decreases to $\sim$ 1.5 J/mol K in presence of 8T magnetic field. Our measurements enable us to estimate the latent heat $L_{CO}$ $\approx$ 235 J/mol involved in the CO transition. Since the entropy of the ferromagnetic metallic (FMM) state is comparable to that of the charge-ordered insulating (COI) state, a subtle change in entropy stabilises either of these two states. Our low temperature specific heat measurements reveal that the linear term is absent in 0T and surprisingly not seen even in the metallic FMM state.
