description: Bacillus spp. endospores are important dormant cell forms and are distributed widely in environmental samples. While these endospores can have important industrial value (e.g. use in animal feed as probiotics), they can also be pathogenic for humans and animals, emphasizing the need for effective endospore detection. Standard spore detection by colony forming units (CFU) is time-consuming, elaborate and prone to error. Manual spore detection by spore count in cell counting chambers via phase-contrast microscopy is less time-consuming. However, it requires a trained person to conduct. Thus, the development of a facilitated spore detection tool is necessary. This work presents two alternative quantification methods: first, a colorimetric assay for detecting the biomarker dipicolinic acid (DPA) adapted to modern needs and applied for Bacillus spp. and second, a model-based automated spore detection algorithm for spore count in phase-contrast microscopic pictures. This automated spore count tool advances manual spore detection in cell counting chambers, and does not require human overview after sample preparation. In conclusion, this developed model detected various Bacillus spp. endospores with a correctness of 85–89%, and allows an automation and time-saving of Bacillus endospore detection. In the laboratory routine, endospore detection and counting was achieved within 5–10 min, compared to up to 48 h with conventional methods. The DPA-assay on the other hand enabled very accurate spore detection by simple colorimetric measurement and can thus be applied as a reference method.

description: We have investigated the electronic and magnetic structures of Sr2FeMoO6 employing site-specific direct probes, namely x-ray absorption spectroscopy with linearly and circularly polarized photons. In contrast to some previous suggestions, the results clearly establish that Fe is in the formal trivalent state in this compound. With the help of circularly polarized light, it is unambiguously shown that the moment at the Mo sites is below the limit of detection (< 0.25mu_B), resolving a previous controversy. We also show that the decrease of the observed moment in magnetization measurements from the theoretically expected value is driven by the presence of mis-site disorder between Fe and Mo sites.

description: A new method has been developed for the correction of the distortions and/or enhanced phase differentiation in Electron Backscatter Diffraction (EBSD) data. Using a multi-modal data approach, the method uses segmented images of the phase of interest (laths, precipitates, voids, inclusions) on images gathered by backscattered or secondary electrons of the same area as the EBSD map. The proposed approach then search for the best transformation to correct their relative distortions and recombines the data in a new EBSD file. Speckles of the features of interest are first segmented in both the EBSD and image data modes. The speckle extracted from the EBSD data is then meshed, and the Covariance Matrix Adaptation Evolution Strategy (CMA-ES) is implemented to distort the mesh until the speckles superimpose. The quality of the matching is quantified via a score that is linked to the number of overlapping pixels in the speckles. The locations of the points of the distorted mesh are compared to those of the initial positions to create pairs of matching points that are used to calculate the polynomial function that describes the distortion the best. This function is then applied to un-distort the EBSD data, and the phase information is inferred using the data of the segmented speckle. Fast and versatile, this method does not require any human annotation and can be applied to large datasets and wide areas. Besides, this method requires very few assumptions concerning the shape of the distortion function. It can be used for the single compensation of the distortions or combined with the phase differentiation. The accuracy of this method is of the order of the pixel size. Some application examples in multiphase materials with feature sizes down to 1 $μ$m are presented, including Ti-6Al-4V Titanium alloy, Rene 65 and additive manufactured Inconel 718 Nickel-base superalloys.

description: We examined the chest CT scans of 1,453 WTC responders using the International Classification of High-resolution CT for Occupational and Environmental Respiratory Diseases. Univariate and bivariate analyses of potential work-related pleural abnormalities were performed with pre-WTC and WTC-related occupational exposure data, spirometry, demographics and quantitative CT measurements. Logistic regression was used to evaluate occupational predictors of those abnormalities. Chest CT scans were performed first at a median of 6.8 years after 9/11/2001. Pleural abnormalities were the most frequent (21.1%) across all occupational groups In multivariable analyses, significant pre-WTC occupational asbestos exposure, and work as laborer/cleaner were predictive of pleural abnormalities, with prevalence being highest for the Polish subgroup (n = 237) of our population. Continued occupational lung disease surveillance is warranted in this cohort.

description: Our objective in this study was to calculate the vehicles flow on GO-341 highway. We also aimed to identify the category of vehicle responsible for increasing traffic and the period of the day with greater traffic.For that, three continuous 24-hour samplings were performed. We recorded a total of 2 083 vehicles in the 72 hours of observation (mean of 694 vehicles every 24 hours). The evaluation of the types of vehicles that transited on the highway pointed out that cars (44.7%) and trucks (45.3%) had a similar frequency, followed by pickup trucks (6.2%) and motorcycles (1.6%), other types of vehicles were less representative (2.2%). From midnight a few vehicles passed on the highway. After 3:00 a.m. this number started to increase until 9:00 a.m., when the vehicles flow started to be more intense until 6:00 p.m. with about 40 to 50 vehicles.

description: The Robust Phase Estimation (RPE) protocol was designed to be an efficient and robust way to calibrate quantum operations. The robustness of RPE refers to its ability to estimate a single parameter, usually gate amplitude, even when other parameters are poorly calibrated or when the gate experiences significant errors. Here we demonstrate the robustness of RPE to errors that affect initialization, measurement, and gates. In each case, the error threshold at which RPE begins to fail matches quantitatively with theoretical bounds. We conclude that RPE is an effective and reliable tool for calibration of one-qubit rotations and that it is particularly useful for automated calibration routines and sensor tasks.

description: The crystallization of undercooled liquid zirconium (Zr) was investigated via molecular dynamics simulations. The atomic structures were characterised and analysed by means of pair distribution function, angular distribution function, and the largest standard cluster analysis. At low temperature (T = 1000 K), it is found that the crystallization begins at the initial stage of relaxation and takes the pathway of undercooled liquid (UCL)→BCC→HCP instead of UCL→HCP. The HCP-type medium-range orders (MROs) are formed from the inside of the precursors formed by the BCC-type MROs, and growing at the cost of the precursors, in agreement with the Ostwald’s step rule. The number of MROs is found to play a key role in forming the crystal phases in this process. However, at high temperature (T = 1200 K) the time-scale to reach crystallization is two orders of magnitude bigger than that of T = 1000 K. No intermediate stage of crystallization is observed. The undercooled Zr melts are directly transformed into BCC crystal phases. The max size of BCC-MROs is intimately correlated with the crystallization.

description: The simultaneous consideration of a numerical model and of different observations can be achieved using data-assimilation methods. In this contribution, the ensemble Kalman filter (EnKF) is applied to obtain the system-state development and also an estimation of unknown model parameters. An extension of the Kalman filter used is presented for the case of uncertain model parameters, which should not or cannot be estimated due to a lack of necessary measurements. It is shown that incorrectly assumed probability density functions for present uncertainties adversely affect the model parameter to be estimated. Therefore, the problem is embedded in a multilayered uncertainty space consisting of the stochastic space, the interval space, and the fuzzy space. Then, we propose classifying all present uncertainties into aleatory and epistemic ones. Aleatorically uncertain parameters can be used directly within the EnKF without an increase in computational costs and without the necessity of additional methods for the output evaluation. Epistemically uncertain parameters cannot be integrated into the classical EnKF procedure, so a multilayered uncertainty space is defined, leading to inevitable higher computational costs. Various possibilities for uncertainty quantification based on probability and possibility theory are shown, and the influence on the results is analyzed in an academic example. Here, uncertainties in the initial conditions are of less importance compared to uncertainties in system parameters that continuously influence the system state and the model parameter estimation. Finally, the proposed extension using a multilayered uncertainty space is applied on a multi-degree-of-freedom (MDOF) laboratory structure: a beam made of stainless steel with synthetic data or real measured data of vertical accelerations. Young’s modulus as a model parameter can be estimated in a reasonable range, independently of the measurement data generation.

description: We analyze the scaling laws for a set of two different species of long flexible polymer chains joined together at one of their extremities (copolymer stars) in space dimension D=2. We use a formerly constructed field-theoretic description and compare our perturbative results for the scaling exponents with recent conjectures for exact conformal scaling dimensions derived by a conformal invariance technique in the context of D=2 quantum gravity. A simple MC simulation brings about reasonable agreement with both approaches. We analyse the remarkable multifractal properties of the spectrum of scaling exponents.

 Acanthagenys rufogularis queenslandicus Mathews, 1912a: 421 (North Queensland).
 Now Acanthagenys rufogularis Gould, 1838. See Salomonsen, 1967: 445, Schodde and Mason, 1999: 295–296, Christidis and Boles, 2008: 185– 191, and Higgins et al., 2008: 618–619.
 HOLOTYPE: AMNH 696558, said by Mathews to have been collected in northern Queensland, Australia. From the Mathews Collection (no. 7771) via the Rothschild Collection.
 COMMENTS: Mathews cited his catalog number of the holotype in the original description and gave the range of queenslandicus as ‘‘North Queensland.’’ The specimen was cataloged by Mathews as a single specimen of this species from the J.A. Thorpe collection, but it no longer has an original label nor any other data on its existing labels. It bears a Mathews and a Rothschild type label and a ‘‘Figured’’ label, indicating that it was illustrated in Mathews (1925a, pl. 553, opp. p. 88, text p. 89), where it is confirmed as the type of queenslandicus. Based on the published description, it is the lower figure in the plate. Both figures in this plate are identified on the plate as females, and the specimen described in Mathews (1925a: 89) is said to be a female, but the specimen is sexed as a male in Mathews’ catalog. Although some of Thorpe’s specimens were collected on Cape York, the majority of them were from New South Wales, and I consider the ‘‘N. Queensland’’ entered by Mathews in his catalog to be questionable, given the absence of an original label. Other specimens in AMNH from the Rothschild Collection collected in north Queensland had never been in the Mathews Collection.

 Notes. The specimen from Socotra is tentatively identified as Trissemus maroccanus wittmeri described from Saudi Arabia (BESUCHET 1981) due to its distribution. As stated in the original description, there is no external character supporting the new subspecies that was described based only on a slightly different structure of the aedeagus. These differences are quite small and may be intraspecific variation rather than a character appropriate to define different subspecies. That is supported also by the structure of the aedeagus of the specimen from Socotra, whose form is somewhat between the two known subspecies. It is highly likely that more material will prove that both subspecies are synonyms.
 Distribution. Saudi Arabia, Yemen. First record from Socotra Island.

Mechanical cane toad traps could be made more native-fauna friendly if they could distinguish invasive cane toads from native species. Here we designed and trained a Convolution Neural Network (CNN) starting from the Xception CNN. The XToadGmp toad-recognition CNN we developed was trained end-to-end using heat-map Gaussian targets. After training, XToadGmp required minimum image pre/post-processing and when tested on 720x1280 shaped images, it achieved 97.1% classification accuracy on 1863 toad and 2892 not-toad test images, which were not used in training.

description: Four-fermion final states qqbar e+e- and qqbar mu+mu- from neutral-current interactions in e+e- collisions are studied in the OPAL detector at LEP at centre-of-mass energies from 183 GeV to 209 GeV. The data analysed correspond to a total integrated luminosity of about 650 pb-1 recorded from 1997 to 2000. Corresponding to the acceptance of the OPAL detector, a signal definition is applied requiring both leptons to have a scattering angle satisfying cos0 <0.95. Further requirements are made on the invariant masses of the fermion pairs. The extracted cross-sections for the processes e+e- -> qqbar e+e- and e+e- qqbar mu+mu- are consistent with the expectations from the Standard Model.

description: We present a first principles investigation of the lattice dynamics and electron-phonon coupling of the superconductor MgB_2 and the isostructural AlB_2 within the framework of density functional perturbation theory using a mixed-basis pseudopotential method. Complete phonon dispersion curves and Eliashberg functions α^2F are calculated for both systems. We also report on Raman measurements, which support the theoretical findings. The calculated generalized density-of-states for MgB_2 is in excellent agreement with recent neutron-scattering experiments. The main differences in the calculated phonon spectra and α^2F are related to high frequency in-plane boron vibrations. As compared to AlB_2, they are strongly softened in MgB_2 and exhibit an exceptionally strong coupling to electronic states at the Fermi energy. The total coupling constants are λ_{MgB_2}=0.73 and λ_{AlB_2}=0.43. Implications for the superconducting transition temperature are briefly discussed.

description: We design a series of quantum circuits that generate absolute maximally entangled (AME) states to benchmark a quantum computer. A relation between graph states and AME states can be exploited to optimize the structure of the circuits and minimize their depth. Furthermore, we find that most of the provided circuits obey majorization relations for every partition of the system, and at every step of the quantum computation. The rational for our approach is to benchmark quantum computers with maximal useful entanglement, which can be used to implement multipartite quantum protocols.

Brignolia sinharaja

description: Brignolia sinharaja, new species Figures 240–268
TYPES: Male holotype and female allotype from the Sinharaja Forest Reserve, Ratnapura, Sri Lanka (Aug. 23, 1981), deposited in NML (PBI_OON 31759).
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
 DIAGNOSIS: Males resemble those of B. bowleri in having the sternum medially depressed, but have the depression largely confined to the posterior half of the sternum (figs. 243, 244); they are easily recognized by the unusually long endite tip and the presence of a second, long process on the lateral edge of the endite (figs. 243, 244, 255, 256). Females have a distinctive, broadly triangular process that fills most of the space between the epigastric furrow and the posterior spiracular groove (figs. 267, 268).
 MALE (PBI_OON 31759, figs. 240–258): Total length 1.49. Carapace brown, without any pattern; pars cephalica strongly elevated in lateral view; posterolateral edge with pair of pits, posterior declivity steep, top margin with three enlarged setae with enlarged bases on each side, posterior margin squared, with pair of dark triangular sclerotizations. Sternum without pits, with median concavity occupying most of sternal length, posterior ridge produced, bearing three large tubercles on each side. Scuto-pedicel region with deeply W-shaped scutal ridge, extremely weak medially but with one enlarged tubercle opposite each pedicel triangle. Palpal bulb with dorsally directed, flattened tip, tip shorter than in B. bowleri.
FEMALE (PBI_OON 31759, figs. 259– 268): Total length 1.37. Posterior sternal ridge less pronounced than in male, bearing only small tubercles. Posterior epigastric area with elaborate sclerotizations; posterior tube long, narrow.
OTHER MATERIAL EXAMINED: None.
DISTRIBUTION: Sri Lanka.

description: We explore the sensitivity and the physics interest of the measurement of parity-violating spin asymmetries in one-jet production in the presence of a new leptophobic neutral gauge boson Z', within polarized hadronic collisions at the BNL RHIC. We focus on polarized neutron collisions which could be achieved in a realistic upgrade of the RHIC-Spin program. We show that, in case of a discovery, a compilation of the information coming from both polarized pp and nn collisions should constrain the number of Higgs doublets and the presence or absence of trilinear fermion mass terms in the underlying model of New Physics.

description: Gerbera jamesonii Bolus ex Hooker F. (Asteraceae), a most prominent ornamental plant ranking fifth in the world cut flower market has gained huge demand across the globe for its high aesthetic value. In the present study, an efficient plant regeneration protocol was developed using capitulum explants from the field grown mature plants of G. jamesonii. A successful surface sterilization procedure was established using a series of sterilants without affecting explant regenerability. The culture of capitulum explants on Pre-culture Induction Medium [(PIM), Murashige and Skoog (MS) medium fortified with 0.5 mg/L thidiazuron (TDZ) in combination with low levels of auxins] for a period of 2 weeks in dark conditions was crucial for inducing morphogenetic response. Upon transfer onto Shoot Regeneration Medium [(SRM), MS +4.0 mg/L 6-benzyladenine (BA) and 0.2 mg/L NAA], explants has significantly produced highest number of shoots (16 ± 0.33). Incubation for 18–21 days on Shoot Multiplication and Elongation Medium [(SMEM), MS +2.0 mg/L BA +0.2 mg/L NAA] resulted in the highest number of multiple shoots (22.00 ± 0.93) with increased mean shoot length (3.49 ± 0.08). In vitro elongated shoots were rooted (95%) on ½ MS +1.0 mg/L indole-3-acetic acid (IAA) within 10–12 days and fully rooted plants were transferred to poly-house for hardening with 90% survival rate.
Sr$_3$CuIrO$_6$, a spin-chain compound with random ferromagnetic-antiferromagnetic interactions

description: Ac and dc magnetization and heat-capacity (C) measurements performed on the pseudo-one-dimensional compound Sr$_3$CuIrO$_6$ reveal a competition between antiferromagnetic (AF) and ferromagnetic (F) exchange couplings, as evidenced by frequency dependence of ac susceptibility and by the absence of a C anomaly at the magnetic transition. The value of the saturation moment (about 0.35 $μ_B$/formula unit) is much smaller than expected for ferromagnetism from the two S=1/2 ions (Cu and Ir). Thus, this compound is not a ferromagnet in zero magnetic field, in contrast to earlier beliefs. Of particular importance is the finding that the value of the magnetic ordering temperature is sample dependent, sensitive to synthetic conditions resulting from deviations in oxygen/Cu content. We propose that this compound serves as a unique model system to test theories on random AF-F interaction in a chain system, considering that this competition can be tuned without any chemical substitution.

description: This piece is the first of new annual feature of the journal, entitled ‘Debate’. Two scholars offer their contrasting reflections on a topic of interest – this year, it is ‘scientific progress, human progress and Christian theology’. The debate is opened by American sociologist Steve Fuller, who briefly presents his thesis on the subject, proposing in the end the Church to be more open to an ‘adventurous approach to nature’ in his opinion more consonant with today’s ‘emerging biometrically oriented genetic science’. In answer, Italian theologian Giuseppe Tanzella-Nitti explains that, from a Christian perspective, human progress needs to respect the ‘ontological foundations of creature itself’ in order to avoid the ‘illusion’ of a false progress. Taking these thoughts into account, Fuller replies clarifying his points. The debate is concluded by remarks from the Editor.
Diffusion of Earthquake Aftershock Epicenters, Omori's Law and Generalized Continuous-Time Random Walk Models

Year: 2002
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The epidemic-type aftershock sequence model (ETAS) is a simple stochastic process modeling seismicity, based on the two best-established empirical laws, the Omori law (power law decay ~1/t^{1+θ} of seismicity after an earthquake) and Gutenberg-Richter law (power law distribution of earthquake energies). In order to describe also the space distribution of seismicity, we use in addition a power law distribution ~1/r^{1+μ} of distances between triggered and triggering earthquakes. We present an exact mapping between the ETAS model and a class of CTRW (continuous time random walk) models, based on the identification of their corresponding Master equations. This mapping allows us to use the wealth of results previously obtained on anomalous diffusion of CTRW. We provide a classification of the different regimes of diffusion of seismic activity triggered by a mainshock. Specifically, we derive the relation between the average distance between aftershocks and the mainshock as a function of the time from the mainshock and of the joint probability distribution of the times and locations of the aftershocks. Our predictions are checked by careful numerical simulations. We stress the distinction between the ``bare'' Omori law describing the seismic rate activated directly by a mainshock and the ``renormalized'' Omori law taking into account all possible cascades from mainshocks to aftershocks of aftershock of aftershock, and so on. In particular, we predict that seismic diffusion or sub-diffusion occurs and should be observable only when the observed Omori exponent is less than 1, because this signals the operation of the renormalization of the bare Omori law, also at the origin of seismic diffusion in the ETAS model.

Determination of the carrier diffusion length in GaN from cathodoluminescence maps around threading dislocations: fallacies and opportunities

description: We investigate, both theoretically and experimentally, the drift, diffusion, and recombination of excitons in the strain field of an edge threading dislocation intersecting the GaN{0001} surface. We calculate and measure hyperspectral cathodoluminescence maps around the dislocation outcrop for temperatures between 10 to 200 K. Contrary to common belief, the cathodoluminescence intensity contrast is only weakly affected by exciton diffusion, but is caused primarily by exciton dissociation in the piezoelectric field at the dislocation outcrop. Hence, the extension of the dark spots around dislocations in the luminescence maps cannot be used to determine the exciton diffusion length. However, the cathodoluminescence energy contrast, reflecting the local bandgap variation in the dislocation strain field, does sensitively depend on the exciton diffusion length and hence enables its experimental determination.

description: Cette thèse vise à analyser les expériences des étudiants au cours de leur processus d’adaptation aux études universitaires. La principale question de recherche est la suivante : Comment le projet vocationnel participe-t-il au processus d’adaptation aux études universitaires ? La recherche a porté sur l’expérience de huit participants. Ceux-ci ont été interviewés à deux moments : dans un premier temps, en 2012, alors qu’ils vivaient la transition des études secondaires aux études universitaires ; dans un deuxième temps, en 2017, à la fin de leurs cursus universitaire. Une analyse qualitative des données a été effectuée. Elle met en évidence le fait que l’accomplissement de certaines tâches d’adaptation facilite le passage de l’école secondaire à l’université. L’analyse qualitative indique également que le processus d’adaptation aux études universitaires commence bien avant l’arrivée à l’université. En fait, idéalement, le passage à l’école secondaire constitue un lieu de préparation aux études universitaires. Et cette préparation se loge surtout à l’enseigne de la construction identitaire.

An adaptive strategy based on conforming quadtree meshes for kinematic limit analysis

description: We propose a simple and efficient scheme based on adaptive finite elements over conforming quadtree meshes for collapse plastic analysis of structures. Our main interest in kinematic limit analysis is concerned with both purely cohesive-frictional and cohesive materials. It is shown that the most computational efficiency for collapse plastic problems is to employ an adaptive mesh strategy on quadtree meshes. However, a major difficulty in finite element formulations is the appearance of hanging nodes during adaptive process. This can be resolved by a definition of conforming quadtree meshes in the context of polygonal elements. Piecewise-linear shape functions enhanced with generalized bubble functions in barycentric coordinates are used to approximate the velocity field. Numerical results prove the reliability and benefit of the present approach.
