description: Abstract: Synchrotron X-ray imaging has been used to examine in situ the deformation of dendrites that takes place during the solidification of a nickel-based superalloy. By combining absorption and diffraction contrast imaging, deformation events could be classified by their localization and permanence. In particular, a deformation mechanism arising from thermal contraction in a temperature gradient was elucidated through digital image correlation. It was concluded that this mechanism may explain the small misorientations typically observed in single crystal castings.

description: We present numerical evidence for the existence of spinning generalizations for non-topological Q-ball solitons in the theory of a complex scalar field with a non-renormalizable self-interaction. To the best of our knowledge, this provides the first explicit example of spinning solitons in 3+1 dimensional Minkowski space. In addition, we find an infinite discrete family of radial excitations of non-rotating Q-balls, and construct also spinning Q-balls in 2+1 dimensions.

description: (La,Ce)OBiS2 single crystals are successfully grown using CsCl flux. The obtained single crystals have a plate-like shape with a size of 0.5-2.0 mm and a well-developed ab-plane. The thickness of the crystals increases with a decrease in the Ce content. The (La,Ce)OBiS2 single crystals exhibit superconducting properties. Moreover, the superconducting transition temperature increases with an increase in the Ce content. The obtained (La,Ce)OBiS2 single crystals exhibit a tetragonal structure and the valence state of Ce in the crystals is determined to be mixed with Ce3+ and Ce4+ based on X-ray absorption fine structure spectroscopy.

description: We provide a Hilbert-Mumford Criterion for actions of reductive groups $G$ on $Q$-factorial complex varieties. The result allows to construct open subsets admitting a good quotient by $G$ from certain maximal open subsets admitting a good quotient by a maximal torus of $G$. As an application, we show how to obtain all invariant open subsets with good quotient for a given $G$-action on a complete $Q$-factorial toric variety.

description: Entomobrya lamingtonensis Schött, 1917
Type locality. QLD, one specimen, Christmas Creek, Glen Lamington, South Queensland, - 28.258°S, 153.011°E, 300m asl., October 1912, Mjöberg leg.
Background. The only specimen of this species is the type deposited in the Riksmuseet Museum in Stockholm, which was examined. Schött’s (1917) description was as follows: “Dark blue. Depigmented patches and stripes especially on the front part of Abd. IV, antennae of the single specimen damaged. Meso- and metanotum roughly equal in length. Abd III. IV =1: 2.33, eyes on a black spot. A tibial tenent hair a little shorter than the head size. Unguis typical with 2 distal teeth, unguiculus gradually tapering. Mucro with 2 teeth, with well-developed anteapical tooth and with basal spine. Chaetae sparse, normal. Length 1.25 mm ”.
This superficial description could apply to any other dark blue Entomobrya known. In the collection of South Australian Museum in Adelaide is deposited the Womersley collection of Entomobrya. In it are several specimens on slides identified by H. Womersley as E. lamingtonensis Schött, 1917 from different localities. Glen Lamington is on the southern boundary of Lamington National Park in eastern Australia, while Womersley’s localities were: Kalorama Memorial Reserve, Dandengong Ranges, and You Yang Mountains both in VIC around 1300 km south of Lamington. One specimen from each locality was available for chaetotaxic examination. These specimens are here identified as Entomobrya clarki. A further five specimens from the Womersley collection identified as E. lamingtonensis were from Waterfall Gully, Mount Lofty Ranges near Adelaide, South Australia, 1500 km south of Lamington and 600 km west of VIC. These specimens are cleared, but probably were dark in life. They have a chaetotaxy that is unique among the described species as do two specimens from Perth, West Australia, 3500 km south west of Lamington. Both these slides carry specimens collected in different years, seven of them also have a different chaetotaxy. Womersley’s identified specimens were compared to the holotype of E. lamingtonensis below.

description: In this paper, we investigate the use of chirp spread spectrum signaling over air-ground channels. This includes evaluation of not only the traditional linear chirp, but also of a new chirp signal format we have devised for multiple access applications. This new format is more practical than prior multi-user chirp systems in the literature, because we allow for imperfect synchronism. Specifically we evaluate multi-user chirp signaling over air-ground channels in a quasi-synchronous condition. The air-ground channels we employ are models based upon an extensive NASA measurement campaign. We show that our new signaling scheme outperforms the classic linear chirp in these air-ground settings.

description: Abstract: Typically we do not add objects in conformal geometric algebra (CGA), rather we apply operations that preserve grade, usually via rotors, such as rotation, translation, dilation, or via reflection and inversion. However, here we show that direct linear interpolation of conformal geometric objects can be both intuitive and of practical use. We present a method that generates useful interpolations of point pairs, lines, circles, planes and spheres and describe algorithms and proofs of interest for computer vision applications that use this direct averaging of geometric objects.

description: Sequence discriminative training criteria have long been a standard tool in automatic speech recognition for improving the performance of acoustic models over their maximum likelihood / cross entropy trained counterparts. While previously a lattice approximation of the search space has been necessary to reduce computational complexity, recently proposed methods use other approximations to dispense of the need for the computationally expensive step of separate lattice creation. In this work we present a memory efficient implementation of the forward-backward computation that allows us to use uni-gram word-level language models in the denominator calculation while still doing a full summation on GPU. This allows for a direct comparison of lattice-based and lattice-free sequence discriminative training criteria such as MMI and sMBR, both using the same language model during training. We compared performance, speed of convergence, and stability on large vocabulary continuous speech recognition tasks like Switchboard and Quaero. We found that silence modeling seriously impacts the performance in the lattice-free case and needs special treatment. In our experiments lattice-free MMI comes on par with its lattice-based counterpart. Lattice-based sMBR still outperforms all lattice-free training criteria.

description: This study was done in order to assess the association between the performance of school-based dental programs (SBDPs) and oral health-related quality of life (OHRQoL) in
school children, in the province of Yogyakarta, Indonesia, taking into account untreated caries and sociodemographic factors. A cross-sectional survey was administered with 1906 children aged 12 and participating in SBDPs. Four SBDPs were chosen to represent good and poor performance in urban and rural areas. Caries was assessed using World Health Organization (WHO) criteria, whereas the children were interviewed for the OHRQoL and sociodemographic data. The OHRQoL was assessed using the Condition-Specific Child-Oral Impact on Daily Performances (CS Child-OIDP) index related to dental caries. The results revealed that the mean CS Child-OIDP score was 1.63 (SD 3.20) for good performance SBDP and 6.89 (SD 8.85) for poor performance SBDP. Analysis by negative binomial regression showed that being served by a poorly performing SBDP (RR = 4.45, 95% CI = 3.87–5.13), and to some extent living in a rural area and being a girl, were significantly associated with a greater risk of having a lower quality of life than were the counterparts. Untreated caries did not show an association with OHRQoL. In conclusion, there are substantial indications that SBDP performance is related to children’s OHRQoL.

description: Abstract: Background: Birds of prey (raptors) are dominant apex predators in terrestrial communities, with hawks (Accipitriformes) and falcons (Falconiformes) hunting by day and owls (Strigiformes) hunting by night. Results: Here, we report new genomes and transcriptomes for 20 species of birds, including 16 species of birds of prey, and high-quality reference genomes for the Eurasian eagle-owl (Bubo bubo), oriental scops owl (Otus sunia), eastern buzzard (Buteo japonicus), and common kestrel (Falco tinnunculus). Our extensive genomic analysis and comparisons with non-raptor genomes identify common molecular signatures that underpin anatomical structure and sensory, muscle, circulatory, and respiratory systems related to a predatory lifestyle. Compared with diurnal birds, owls exhibit striking adaptations to the nocturnal environment, including functional trade-offs in the sensory systems, such as loss of color vision genes and selection for enhancement of nocturnal vision and other sensory systems that are convergent with other nocturnal avian orders. Additionally, we find that a suite of genes associated with vision and circadian rhythm are differentially expressed in blood tissue between nocturnal and diurnal raptors, possibly indicating adaptive expression change during the transition to nocturnality. Conclusions: Overall, raptor genomes show genomic signatures associated with the origin and maintenance of several specialized physiological and morphological features essential to be apex predators.
Entropic Priors for Discrete Probabilistic Networks and for Mixtures of Gaussians Models

description: The ongoing unprecedented exponential explosion of available computing power, has radically transformed the methods of statistical inference. What used to be a small minority of statisticians advocating for the use of priors and a strict adherence to bayes theorem, it is now becoming the norm across disciplines. The evolutionary direction is now clear. The trend is towards more realistic, flexible and complex likelihoods characterized by an ever increasing number of parameters. This makes the old question of: What should the prior be? to acquire a new central importance in the modern bayesian theory of inference. Entropic priors provide one answer to the problem of prior selection. The general definition of an entropic prior has existed since 1988, but it was not until 1998 that it was found that they provide a new notion of complete ignorance. This paper re-introduces the family of entropic priors as minimizers of mutual information between the data and the parameters, as in [rodriguez98b], but with a small change and a correction. The general formalism is then applied to two large classes of models: Discrete probabilistic networks and univariate finite mixtures of gaussians. It is also shown how to perform inference by efficiently sampling the corresponding posterior distributions.

description: Solitary zonal structures have recently been identified in gyrokinetic simulations of subcritical drift-wave (DW) turbulence with background shear flows. However, the nature of these structures has not been fully understood yet. Here, we show that similar structures can be obtained within a reduced model, which complements the modified Hasegawa-Mima equation with a generic primary instability and a background shear flow. We also find that these structures can be qualitatively reproduced in the modified Hasegawa-Wakatani equation, which subsumes the reduced model as a limit. In particular, we illustrate that in both cases, the solitary zonal structures approximately satisfy the same ''equation of state'', which is a local relation connecting the DW envelope with the zonal-flow velocity. Due to this generality, our reduced model can be considered as a minimum model for solitary zonal structures in subcritical DWs.

Subjects: subject: 70799 Veterinary Sciences not elsewhere classified

description: Relapse is considered a significant failure after orthodontic treatment. In response to
relapse, RANKL expressions will increase, while OPG expressions will decrease. CHA is thought
to be one of an ideal candidate for enhancing bone formation. Moreover, aPRF is a source high
levels of growth factors that play a central role in the bone remodeling. This research was intended
to investigate the effect of hydrogel CHA-aPRF in preventing relapse. Hydrogel-CHA was initially
designed, with its degradation profile and FTIR (Fourie’s Transform Infrared) spectra were
investigated as the basis to find out optimum formulation before incorporated with aPRF. Hydrogel-
CHA microspheres were prepared in 3 different compositions: those were encoded 30-CHA,
40-CHA, and 50-CHA. After the hydrogel formulation and characterization were completed, 10 mL
blood samples were collected, then centrifuged at 1500 rpm for 14 min. At the end of the
centrifugation process, the aPRF clot was isolated and then pressed to obtain their releasate. The
releasate aPRF was then loaded into the best formulation candidate of hydrogel CHA. The hydrogel
incorporated aPRF was then gently injected on the mesial side of incisor gingival sulcus of the
rabbit after orthodontic tooth movement. The FTIR analysis showed that carbonated apatite was
successfully developed during the fabrication process of hydrogel-CHA microspheres. It was also
known that degradation profile of 30-CHA was considered ideal compared to the other
compositions. The application of CHA-aPRF (group C) was proven to significantly prevent relapse,
indicated by lowest percentage of relapse 21 days after debonding (29.95±3.91%) compared to
control group. Furthermore, it has been found that expressions of RANKL were significantly lowest
(p<0.05) in group C on day 0, 3, and 7, while OPG expressions showed significantly highest
(p<0.05) in group C on day 14 and 21 after debonding. These results indicate that incorporation of
hydrogel-CHA has potential effect to enhance alveolar bone remodeling and prevent orthodontic
relapse by stimulates OPG expression and suppresses RANKL expression.

description: In this paper, we present the laboratory study on three experimental setups that produce a free arc channel subjected to the transient phase of a lightning current waveform. This work extends the high-current pulsed arc characterization performed in previous studies for peak levels up to 100 kA. Eleven high-current waveforms with peak value ranging from 100--250 kA with different growth rates and action integrals are studied, allowing the comparison of different test benches. These waveforms correspond to standard lightning ones used in aircraft certification processes. Hydrodynamic properties such as arc channel evolution and shock-wave propagation are determined by high-speed video imaging and the background-oriented Schlieren method. The arc diameter reaches around 90mm at 50 $μ$s for a current of 250 kA peak. Space- and time-resolved measurements of temperature, electron density and pressure are assessed by optical emission spectroscopy associated with the radiative transfer equation. It is solved across the arc column and takes into account the assumption of non-optically thin plasma at local thermodynamic equilibrium. For a 250 kA waveform, temperatures up to 43000K are found, with pressures in the order of 50 bar. The influence of current waveform parameters on the arc properties are analyzed and discussed.

 Meteorus tenuicornis Thomson, 1895:2164. Lectotype ♀, Sweden: Skåne, Pålsjö (ZI, Lund)—examined
 Diagnosis: Meteorus jaculator is similar to M. cis and M. vexator. However, M. vexator is easily distinguished from the other two based on the strongly converging eyes. The eyes are only slightly converging in the other two species, which are most easily distinguished by the length of the ovipositor. M. jaculator has an ovipositor length of 3–4 times the length of the petiolar tergum, whereas M. cis has a much shorter ovipositor, only 2 times the length of the petiolar tergum.
 Studied material: ~ 20 specimens.
 Description: Size about 3mm. Antennae short, 18–22 articles, slender. Head swollen behind eyes; temples longer than eyes. Ocelli small, OOL=3–4. Eyes small, slightly convergent. Malar space at least slightly shorter than basal breadth of mandible. Face about twice as broad as high, protuberant. Clypeus wide as face and smooth, with scattered large punctures, not strongly protuberant. Tentorial pits small. Mandibles stout, slightly twisted. Precoxal sulcus narrow. Propodeum with weak but distinct carinae. The medial longitudinal area of the petiolar tergum is strongly raised ending apically in reticulate rugosity. Ovipositor 3–4 times length of petiolar tergum. Hind coxa often strongly rugose. Tarsal claws short with no basal lobe. Colour dark brown to black; legs testaceous but sometimes the coxae darker; clypeus and mandibles often yellow. Male same as female except that the antennae are much longer, up to 29 articles, all flagellar articles conspicuously longer than broad. Fore wing vein r is as long as vein 3–SR and m-cu antefurcal.
 Distribution: Western Palearctic. Country records: Austria; Bulgaria; Croatia; Czechoslovakia; Denmark; Finland; France; Germany; Hungary; Ireland; Netherlands; Norway; Poland; Russia; Slovakia; Sweden; Switzerland; Turkey; United Kingdom; Yugoslavia.
 Biology: M. jaculator is recorded as being a parasitoid on three lepidopteran families (Gelechiidae, Psychidae and Tineidae) (Yu et al. 2005). We found 6 specimens within the SMTP. They were caught from July to October in northern Sweden, predominantly in deciduous forests.

Thus, there is a need for modeling formalisms that can accommodate all available data, even if uncertain, in order to employ them and build useful models. This paper shows how the Flexible Nets (FNs) formalism can be exploited to handle uncertain parameters while offering attractive analysis possibilities. FNs are composed of two nets, an event net and an intensity net, that model the relation between the state and the processes of the system. While the event net captures how the state of the system is updated by the processes in the system, the intensity net models how the speed of such processes is determined by the state of the system. Uncertain parameters are accounted for by sets of inequalities associated with both the event net and the intensity net. FNs are not only demonstrated to be a valuable formalism to cope with system uncertainties, but also to be capable of modeling different system features, such as resource allocation and control actions, in a facile manner.

description: Modern political marketing managements of parties, government and parliament have gradually taken place within and across democratic countries those ruled under either the parliamentary government or presidential government systems. Little attention however, has been directed to explore the extent to which modern political marketing management of parliament has taken place within countries those run under the presidential system of government especially Indonesia. As led by hypothetical-inductive approach, this work has been specifically directed to explore: a) the dynamic exchanges and interactions; b) the nature and structure of political market arenas; c) types of political products; and d) models of political marketing management of the Indonesian parliament/ the Indonesian House of Representative. Having them, this work goes into the extent to which the institutional marketing management strategies has been advanced by the Indonesian Parliament/the Indonesian House of Representative since Post-New Order Soeharto up to SBY’ governments era (2004-2014).

description: In this article we present the complete massless and massive one-loop triangle diagram results using the negative dimensional integration method (NDIM). We consider the following cases: massless internal fields; one massive, two massive with the same mass m and three equal masses for the virtual particles. Our results are given in terms of hypergeometric and hypergeometric-type functions of external momenta (and masses for the massive cases) where the propagators in the Feynman integrals are raised to arbitrary exponents and the dimension of the space-time D. Our approach reproduces the known results as well as other solutions as yet unknown in the literature. These new solutions occur naturally in the context of NDIM revealing a promising technique to solve Feynman integrals in quantum field theories.

description: We consider a nonlinear implicit evolution inclusion driven by a nonlinear, nonmonotone, time-varying set-valued map and defined in the framework of an evolution triple of Hilbert spaces. Using an approximation technique and a surjectivity result for parabolic operators of monotone type, we show the existence of a periodic solution.

description: Conservation agriculture (CA) has been promoted as sustainable agricultural system which can increase food production with economic use of resources and negligible impact on the environment. Given the well-established benefits of packaged technologies (defined as a collection of technologies/practices that fall under the three themes of CA), adoption as a package has not picked up in South Asia and Sub Saharan Africa. Surprisingly, various isolated components of CA technologies, such as zero tillage drill, land laser leveling, direct seeded rice have been popular in this region. However, considering just a single CA technology would be unjustifiable as this would under-estimate the actual complementary nature of various technologies/practices. Under “partial” adoption and abandonment of CA technologies/practices in Nepal, India and Bangladesh, we found that social networks played an influential role both in the adoption and abandonment decisions while involvement of spouses only influenced the adoption of CA technologies/practices. These factors were found to positively influence adoption and negatively influence abandonment of CA. Results also reveal that education, better quality of information, labor constraints increase adoption of CA technologies/practices. Whereas, land constraints, credit constraints and poor quality of information are more likely to push towards abandonment of CA technologies/practices.

description: Reductive adsorption of [AuCl4]-– by using ascorbic acid immobilized on Mg/Al hydrotalcite (Mg/Al HT) and synthesis of gold nanoparticles (AuNPs) from the reduced gold using sodium citrate have been conducted. Mg/Al HT was synthesized by co-precipitation method at pH 10 with molar ratio of Mg(II) and Al(III) 2:1. Ascorbic acid (AA) was then immobilized on Mg/Al HT to form hybrid of AA and Mg/Al HT (Mg/Al HT-AA). Mg/Al HT-AA was used to reductively adsorb [AuCl4]– and the formed Au(0) was extracted by using sodium citrate to form citrate-capped AuNPs. The formation of AuNPs from 100 mg/L [AuCl4]– solution removed by 60 mg Mg/Al HT-AA was optimum at pH 5.0, by using 70 mM sodium citrate and 2 h sonication time. This optimum condition was successfully applied to synthesize AuNPs from [AuCl4]– as the leaching product of gold from PCB using aquaregia.

description: We consider a quantum system of non-interacting fermions at temperature T, in the framework of linear response theory. We show that semiclassical theory is an appropriate framework to describe some of their thermodynamic properties, in particular through asymptotic expansions in $\hbar$ (Planck constant) of the dynamical susceptibilities. We show how the closed orbits of the classical motion in phase space manifest themselves in these expansions, in the regime where T is of the order of $\hbar$.

description: We present a compressive sensing approach for the long standing problem of Matsubara summation in many-body perturbation theory. By constructing low-dimensional, almost isometric subspaces of the Hilbert space we obtain optimum imaginary time and frequency grids that allow for extreme data compression of fermionic and bosonic functions in a broad temperature regime. The method is applied to the random phase and self-consistent $GW$ approximation of the grand potential. Integration and transformation errors are investigated for Si and SrVO$_3$.

description: To develop new phenazine carboxylic acid derivatives with better phloem mobility, five novel 7-amino acid substituted phenazine-1-carboxylic acids were synthesised by introducing amino acids into PCA at the 7-position. The phloem mobility experiments in Ricinus communis seedlings showed that retaining the carboxyl group of PCA and conjugating amino acids to its phenazine ring can also endow PCA with phloem mobility. Comparing our previous research, we found the amino acids substituted at 7-position on phenazine ring of PCA could clearly enhance the phloem mobility of PCA than that of amino acids conjugated with carboxyl group. Especially, the phloem transport concentration of the compound 7-L-isoleucine substituted PCA (7d) was 21 times higher than PCA-L-isoleucine conjugate (8d). These data suggest that the introduction of amino acids at different structural sites on the phenazine ring could effectively enhance the phloem mobility of PCA and it is worth a further study.

description: The inclusion of two-body exchange currents in the constituent quark model leads to several new relations between the electromagnetic form factors of the nucleon and Delta(1232). These are:(i) the neutron charge form factor can be expressed as the difference between proton and Delta+ charge form factors, and (ii) the N->Delta charge quadrupole (C2) transition form factor is connected to the charge monopole (C0) form factor of the neutron. The latter relation is used to estimate the charge radius of constituent quarks. Furthermore, we find that exchange currents do not modify the SU(6) relation between the magnetic N->Delta and the magnetic neutron form factors. Consequently, after including exchange currents, the C2/M1 ratio in the N->Delta transition can be expressed as a ratio of the elastic charge and magnetic form factors of the neutron.

description: Despite the surge of deep learning, deploying the deep learning-based pedestrian detection into the real system faces hurdles, mainly due to the huge resource usages. The classical feature-based detection system still becomes feasible option. There have been many efforts to improve the performance of pedestrian detection system. Among many feature set, Histogram of Oriented Gradient seems to be very effective for person detection. In this research, various machine learning algorithms are investigated for person detection. Different machine learning algorithms are evaluated to obtain the optimal accuracy and speed of the system.

description: The Waimea Plains (Tasman District, New Zealand) is a major horticulture area, highly reliant on irrigation. Irrigators draw water from an integrated surface water and groundwater system. Fresh water is over-allocated by 64%. Irrigators face significant restrictions due to natural fluctuations in river flow and groundwater levels, i.e. water is unreliable. This case study evaluates different options to address these problems. A catchment optimisation model is used to assess the benefits from enabling water permit transfers and from the proposed Waimea Community Dam (‘the dam’). A spreadsheet model is used to assess the impact of different ways of cutting back water permits, should the dam not go ahead. The case study is based on farm- and orchard-level models which estimate irrigation need, profit and nitrogen leaching under different levels of water allocation, reliability and soil type for apples, viticulture, market gardening and dairy farming over a period of 40 years. Key findings are that: • water permit transfers would result in moderate benefits on average (8.6% increase in average profit) but significant benefits in dry years (46% increase in profit); • the dam would result in significant benefits by enabling expansion of irrigated areas and conversion from unirrigated pasture to higher value crops, and providing a reliable water supply for existing and future irrigators (103% increase in average profit and 10% decrease in nitrogen leaching). • Should the dam not go ahead, water permit cuts based on irrigation need would result in lower, and a more even distribution of, costs than flat-rate cuts.
