description: The problem of community detection in networks is usually formulated as finding a single partition of the network into some “correct” number of communities. We argue that it is more interpretable and in some regimes more accurate to construct a hierarchical tree of communities instead. This can be done with a simple top-down recursive partitioning algorithm, starting with a single community and separating the nodes into two communities by spectral clustering repeatedly, until a stopping rule suggests there are no further communities. This class of algorithms is model-free, computationally efficient, and requires no tuning other than selecting a stopping rule. We show that there are regimes where this approach outperforms K-way spectral clustering, and propose a natural framework for analyzing the algorithm’s theoretical performance, the binary tree stochastic block model. Under this model, we prove that the algorithm correctly recovers the entire community tree under relatively mild assumptions. We apply the algorithm to a gene network based on gene co-occurrence in 1580 research papers on anemia, and identify six clusters of genes in a meaningful hierarchy. We also illustrate the algorithm on a dataset of statistics papers. Supplementary materials for this article are available online.

description: The Engineering Development Array (EDA) is a single test station for Square Kilometre Array (SKA) precursor technology. We have used the EDA to detect low-frequency radio recombination lines (RRLs) from the Galactic Centre region. Low-frequency RRLs are an area of interest for future low-frequency SKA work as these lines provide important information on the physical properties of the cold neutral medium. In this project we investigate the EDA, its bandpass and the radio frequency interference environment for low-frequency spectroscopy. We present line spectra from 30 to 325 MHz for the Galactic Centre region. The decrease in sensitivity for the EDA at the low end of the receiver prevents carbon and hydrogen RRLs to be detected below 40 and 60 MHz respectively. RFI strongly affects frequencies in the range 276-292, 234-270, 131-138, 95-102 and below 33 MHz. Cn$α$ RRLs were detected in absorption for quantum levels n = 378 to 550 (39-121 MHz) and in emission for n = 272 to 306 (228-325 MHz). Cn$β$ lines were detected in absorption for n = 387 to 696 (39-225 MHz). Hn$α$ RRLs were detected in emission for n = 272 to 480 (59-325 MHz). Hn$β$ lines were detected for n = 387 to 453 (141-225 MHz). The stacked Hn$α$ detection at 63 MHz is the lowest frequency detection made for hydrogen RRLs and shows that a cold (partially) ionized medium exists along the line of sight to the Galactic Centre region. The size and velocity of this cold H$^{+}$ gas indicates that it is likely associated with the nearby Riegel-Crutcher cloud.

Properties of Relativistic Jets in Gamma-Ray Burst Afterglows

description: We extend our calculation of physical parameters of GRB jets by modeling the broadband emission of the afterglows 970508, 980519, 991208, 000926, 000418, and 010222. Together with 990123, 990510, 991216, and 000301c, there are ten well-observed afterglows for which the initial opening angle of the GRB jet can be constrained. The jet energies (after the GRB phase) obtained for this set of afterglows are within one decade around 5E50erg. With the exception of 000418, which requires a jet wider than 1/2 radians, the jet initial half-angle in the other cases ranges from 2 deg to 20 deg. We find that, in half of the cases, a homogeneous ambient medium accommodates the afterglow emission better than the wind-like 1/r^2 profile medium expected around massive stars. The two types of media give fits of comparable quality in four cases, a wind medium providing a better description only for 970508. The circumburst densities we obtain are in the 0.1-100 per cc range, with the exception of 990123, for which it is below 0.01 per cc. If in all ten cases the observed GRB durations are a good measure of the ejecta deceleration timescale, then the parameters obtained here lead to jet initial bulk Lorentz factors between 70 and 300, anticorrelated with the jet initial aperture, and jet masses around 1E-6 M_sun. Our results on the jet energy, opening Lorentz factor, and evacuation of material until break-out provide constraints on theoretical models of GRB jets.

description: La présente recherche vise à analyser les motivations des producteurs et des transformateurs à participer aux contrats de production du riz au Bénin. Contrairement aux recherches précédentes, celle-ci compare les préférences des producteurs pour les attributs des contrats à celles des transformateurs qui proposent ces contrats pour s’approvisionner en riz paddy. Les données ont été collectées auprès de 300 producteurs et de 140 transformateurs, de riz sélectionnés aléatoirement. Une estimation du modèle logit conditionnel (LC) indique que les producteurs préfèrent des contrats avec des modes de payement direct, avec préfinancement, avec des prix de vente supérieur au prix de marché. Quant aux transformateurs, ils préfèrent le contraire. En outre, les producteurs préfèrent des contrats spécifiant une pénalité au partenaire commercial en cas de non-achat de la quantité convenue dans les contrats, mais rejettent des contrats spécifiant des pénalités pour eux. Les producteurs de riz sont prêts à effectuer une réduction de 25,8 et de 6,64 FCFA/kg sur le prix du paddy pour que le contrat spécifie respectivement un mode de payement comptant et un préfinancement de la production. En réponse, les transformateurs préfèrent réduire le prix du kg de paddy, de 4,91 et 19,48 FCFA respectivement pour le mode de payement direct et le préfinancement de la production. Les transformateurs sont prêts à payer un montant supplémentaire de 15,13 FCFA/kg pour un paddy de qualité.
Complete treatment of single-photon emission in planar channeling

description: Approximate solutions of the Dirac equation are found for ultrarelativistic particles moving in a periodic potential, which depends only on one coordinate, transverse to the largest component of the momentum of the incoming particle. As an example we employ these solutions to calculate the radiation emission of positrons and electrons trapped in the planar potential found between the (110) planes in Silicon. This allows us to compare with the semi-classical method of Baier, Katkov and Strakhovenko, which includes the effect of spin and photon recoil, but neglects the quantization of the transverse motion. For high-energy electrons, the high-energy part of the angularly integrated photon energy spectrum calculated with the found wave functions differs from the corresponding one calculated with the semi-classical method. However, for lower particle energies it is found that the angularly integrated emission energy spectra obtained via the semi-classical method is in fairly good agreement with the full quantum calculation except that the positions of the harmonic peaks in photon energy and the photon emission angles are shifted.

Chelipeds unequal in size, hand of larger chela with 1 or 2 small tubercles on inner surface. Pereopods 2–4 with deep incisions on anterior margins; these hidden by setae. Abdomen bulbous, visible in dorsal view. Carapace length 18.3 mm.

 Range. Washington; Cape Mendocino, California to San Jeronimo I., Baja California but uncommon south of Monterey Bay, California. Type locality Monterey, California.
 Remarks. Schmitt (1921) cited H. grebnitzkii Schalfeev, 1892 from "Humboldt Bay, California.” There are no other reports of the species from California. Hart (1982) gave the southern geographic limit of this species as Puget Sound, Washington. The record by Schmitt may have come from Humboldt Bay, Alaska instead of California (J. Haig, pers. comm.)
 Hendrickx & Harvey (1999) reported H. cavicauda from Guaymas, Sonora, Gulf of California. This record surely is in error. This may be a misidentification of Petrolisthe s hirtipes Lockington, 1878 (Porcellanidae).

description: Charge doping in transition metal dichalcogenide is currently a subject of high importance for future electronic and optoelectronic applications. Here we demonstrate chemical doping in CVD grown monolayer (1L) of WS2 by a few commonly used laboratory solvents by investigating the room temperature photoluminescence (PL). The appearance of distinct trionic emission in the PL spectra and quenched PL intensities suggest n-type doping in WS2. The temperature-dependent PL spectra of the doped 1L-WS2 reveal significant enhancement of trion emission intensity over the excitonic emission at low temperature indicating the stability of trion at low temperature. The temperature dependent exciton-trion population dynamic has been modeled using the law of mass action of trion formation. These results shed light on the solution-based chemical doping in 1L WS2 and its profound effect on the photoluminescence which is essential for the control of optical and electrical properties for optoelectronics applications.

description: This paper brings deep learning at the forefront of research into Time Series Classification (TSC). TSC is the area of machine learning tasked with the categorization (or labelling) of time series. The last few decades of work in this area have led to significant progress in the accuracy of classifiers, with the state of the art now represented by the HIVE-COTE algorithm. While extremely accurate, HIVE-COTE cannot be applied to many real-world datasets because of its high training time complexity in O(N2 * T4) for a dataset with N time series of length T. For example, it takes HIVE-COTE more than 8 days to learn from a small dataset with N = 1500 time series of short length T = 46. Meanwhile deep learning has received enormous attention because of its high accuracy and scalability. Recent approaches to deep learning for TSC have been scalable, but less accurate than HIVE-COTE. We introduce InceptionTime - an ensemble of deep Convolutional Neural Network (CNN) models, inspired by the Inception-v4 architecture. Our experiments show that InceptionTime is on par with HIVE-COTE in terms of accuracy while being much more scalable: not only can it learn from 1,500 time series in one hour but it can also learn from 8M time series in 13 hours, a quantity of data that is fully out of reach of HIVE-COTE.

Cyclotron resonances (CR) were observed for q-(BEDT-TTF)2I3 and (BEDT-TTF)3Br(pBIB), while periodic orbit resonances (POR) were observed for (BEDT-TTF)2Br(DIA) and (BEDT-TTF)3Cl(DFBIB). The selection of the resonance seems to correspond with the skin depth for each sample. The effective mass of POR seems to have a mass enhancement due to the many-body effect, while effective mass of CR is independent of the strength of the electron-electron interaction. The scattering time deduced from each resonance's linewidth will be also presented.

description: We present an analysis of the second epoch HST WFC3 F110W near-Infrared (NIR) imaging data of the globular cluster M4. The new dataset suggests that one of the previously suggested four brown dwarf candidates in this cluster is indeed a high-probability cluster member. The position of this object in the NIR colour magnitude diagrams (CMDs) is in the white dwarf/brown dwarf area. The source is too faint to be a low-mass main sequence star, but, according to theoretical considerations, also most likely somewhat too bright to be a bona-fide brown dwarf. Since we know that the source is a cluster member, we determined a new optical magnitude estimate at the position the source should have in the optical image. This new estimate places the source closer to the white dwarf sequence in the optical-NIR CMD and suggests that it might be a very cool (T_eff < 4500 K) white dwarf at the bottom of the white dwarf cooling sequence in M4, or a white dwarf/brown dwarf binary. We cannot entirely exclude the possibility that the source is a very massive, bright brown dwarf, or a very low-mass main sequence star, however, we conclude that we still have not convincingly detected a brown dwarf in a globular cluster, but we expect to be very close to the start of the brown dwarf cooling sequence in this cluster. We also note that the main sequence ends at F110W approx.22.5 mag in the proper-motion cleaned CMDs, where completeness is still high.

description: Cette étude utilise une approche semi-paramétrique en deux étapes dans un cadre de fonction de distance directionnelle pour évaluer l’influence du budget d’autofinancement sur l’inefficience technique pure des producteurs de maïs au Bénin. En premier lieu, l’inefficience technique pure a été estimée avec la méthode DEA. Ensuite, les niveaux d’inefficience technique pure obtenus ont été expliqués par le budget d’autofinancement et des facteurs environnementaux en utilisant la régression bootstrap tronquée unique. Les analyses empiriques ont été effectuées sur 151 producteurs de maïs. Les résultats d’inefficience ont montré que seulement 20,53% des producteurs de maïs sont techniquement efficients. Le modèle DEA a aussi indiqué que les producteurs peuvent améliorer leur efficience en augmentant leur niveau de production actuelle et en réduisant simultanément leur usage actuel d’intrants de 26%. L’analyse des sources de l’inefficience a révélé que le budget d’autofinancement affecte négativement et faiblement l’inefficience technique pure des producteurs. En conséquence, les politiques visant à réduire la contrainte de budget sont nécessaires pour améliorer l’efficience technique des producteurs de maïs au Bénin.

description: Radiative cooling is an important ingredient in hydrodynamical models involving evolution of high temperature plasmas. Unfortunately, calculating an accurate cooling coefficient generally requires the solution of over a hundred differential equations to follow the ionization. We discuss here a simple 2-parameter approximation for the cooling coefficient due to elements heavier than H and He, for the temperature range $T= 10^{4}-10^{8}$K. Tests of the method show that it successfully tracks the ionization level in severe dynamical environments, and accurately approximates the non-equilibrium cooling coefficient of the trace elements, usually to within 10% in all cases for which cooling is actually important. The error is large only when the temperature is dropping so rapidly due to expansion that radiative cooling is negligible, but even in this situation, the ionization level is followed sufficiently accurately. The current approximation is fully implemented in publicly available FORTRAN code. A second paper will discuss general approaches to approximation methods of this type, other realizations which could be even more accurate, and the potential for extension to calculations of non-equilibrium spectra.

description: Today, Nigeria is the first economic power of Africa. It is thus a rich country with regard to its climate, precipitation, varieties of grounds, the surface of arable land, and size of its population and has the potential required becoming the nourishing earth of Africa. However, Nigeria records an overdrawn trade balance, 70 % of its population is considered as poor man and 6 % is underfed. It is due to mismanagement of the available resources as well as to an inadequacy of agricultural policies. The main result of the study is that Nigeria will can in a near future, if the fight against the disorder is won, to fill the excess demands of vegetable culture of its African partners if it increases substantially the cultivated surfaces. As regards the products of fishing and the breeding, this country requires standing out the implementation of renovation policies of more or less long duration. The used data are the ones going from 1960 till 2013, before the Boko Haram sect perturbs strongly the economy of Nigeria.

description: In this paper we determine the irreducible components of the Hilbert schemes H(4,g) of locally Cohen-Macaulay space curves of degree four and arbitrary arithmetic genus g. We show that these Hilbert schemes are connected, in spite of having about g^2/24 irreducible components. For g < -2 we exhibit a component that is disjoint from the component of extremal curves and use this to give a counterexample to a conjecture of Ait-Amrane and Perrin.

description: Cet article fait une analyse comparative des résultats économiques de la production rizicole durant la saison B 2014 dans les trois pays de la CEPGL qui sont la République Démocratique du Congo, le Rwanda et le Burundi. L’approche comparative permet de trouver les explications des différences des résultats en partie dans les politiques mises en oeuvre dans chaque pays. Les enquêtes ont été menées dans la plaine de la Ruzizi partagée entre les trois pays auprès de 240 producteurs du riz choisi à partir de la méthode des quotas sur la base d'une stratification des exploitations rizicoles. Dans le site congolais (où il est plus difficile d’accéder aux intrants et crédits), les coûts de production d’1kg de paddy sont les plus élevés avec une fonction de production y=0,034x+0,053z+0,422 et le rendement le plus bas (2698kgs). Par contre, dans les sites burundais et rwandais où l’Etat intervient dans l’approvisionnement en intrants et particulièrement dans le site rwandais, l’accès aux crédits, les fonctions de production sont respectivement de y=0,024x+0,031z+0,297 et y=0,017x+0,023z+0,269 avec des rendements de 3962kgs et 5339kgs dans le même ordre. Les coûts de production supportés sur un hectare rizicole ou encore pour la production d’une tonne de paddy varient selon le pays car ils dépendent de la valeur des intrants utilisés et des autres charges de structures. Ils varient ainsi de 1139,4USD à 1354,5USD/ ha et de 269 à 422USD/tonne.

description: Estimations and applications of factor models often rely on the crucial condition that the number of latent factors is consistently estimated, which in turn also requires that factors be relatively strong, data are stationary and weakly serially dependent, and the sample size be fairly large, although in practical applications, one or several of these conditions may fail. In these cases, it is difficult to analyze the eigenvectors of the data matrix. To address this issue, we propose simple estimators of the latent factors using cross-sectional projections of the panel data, by weighted averages with predetermined weights. These weights are chosen to diversify away the idiosyncratic components, resulting in “diversified factors.” Because the projections are conducted cross-sectionally, they are robust to serial conditions, easy to analyze and work even for finite length of time series. We formally prove that this procedure is robust to over-estimating the number of factors, and illustrate it in several applications, including post-selection inference, big data forecasts, large covariance estimation, and factor specification tests. We also recommend several choices for the diversified weights. Supplementary materials for this article are available online.

description: For exploring novel natural product-derived herbicides, 16 novel α-campholenic aldehyde-based 4-methyl-1,2,4-triazole-thioether compounds were designed, synthesized, and characterized by FT-IR, 1H NMR, 13C NMR, ESI-MS and elemental analysis. The preliminary bioassay showed that, at 100 µg/mL, most of the target compounds displayed significant inhibition activity against root-growth of rape(Brassica campestris L.), with inhibition rates of 85.0%～98.2%(A-class activity level), much better than that of the positive control flumioxazin. In addition, an effective and reasonable 3D-QSAR model was established by CoMFA method in SYBYL-X 2.1.1 software. It was found that, the steric field was the major factor towards the herbicidal activity of the target compounds against B. campestris L., and the introduction of bulky groups into m- and p-position of the benzene ring was favourable to increase the herbicidal activity. This kind of title compounds deserved further study as potential leading compounds for the discovery and development of novel herbicidal agents.

description: The spatial fluctuations of a superfluid flowing in a weak random potential are investigated. We employ classical field theory to demonstrate that the disorder-averaged nonequilibrium second-order correlation of the order parameter at zero temperature is identical to the thermally averaged equilibrium counterpart of a uniform superfluid at an effective temperature. The physics behind this equivalence is that scattering of a moving condensate by disorder has the same effect on the correlation function as equilibrium thermal excitations. The correlation function exhibits an exponential decay in one dimension and a power-law decay in two dimensions. We show that the effective temperature can be measured in an interference experiment of ultracold atomic gases.

Formation of internal shock waves in bent jets

description: We discuss the circumstances under which the bending of a jet can generate an internal shock wave. The analysis is carried out for relativistic and non-relativistic astrophysical jets. The calculations are done by the method of characteristics for the case of steady simple waves. This generalises the non-relativistic treatment first used by Icke (1991). We show that it is possible to obtain an upper limit to the bending angle of a jet in order not to create a shock wave at the end of the curvature. This limiting angle has a value of 75 degrees for non-relativistic jets with a polytropic index k = 4/3, 135 degrees for non-relativistic jets with k = 5/3) and 50 degrees for relativistic jets with k = 5/3. We also discuss under which circumstances jets will form internal shock waves for smaller deflection angles.
