A comparison of the Ranging behaviour and habitat use of the Ethiopian hedgehog (Paraechinus aethiopicus) in Qatar with hedgehog taxa from temperate environments
Authors: Pettett Carly E. , Al-Hajri Afra , Al-Jabiry Hayat , Macdonald David W. , Yamaguchi Nobuyuki
Published: December 2018

We investigated seasonal changes in the ecology and behaviour of the Ethiopian hedgehog (Paraechinus aethiopicus) in Qatar, particularly in respect to differences in behaviour between hedgehogs living in arid environments and hedgehogs in temperate mesic environments. These comparisons will allow us to explore behavioural adaptations to different environments across hedgehog taxa. We radio-tracked 30 hedgehogs in Qatar over two years, and measured home range size, habitat preference, travel speed, activity and body mass. Whilst we found no difference in body mass between males and females, male home range size was over twice as large as that for females. Unlike hedgehogs in Europe, males maintained large home ranges during the non-breeding season. This behaviour may be sustained by the low cost of maintaining a large home range; males travelled less far per hour during the non-breeding season. Habitat use was non-random; arid areas with human influence, including rubbish dumping sites, was the most selected habitat type compared with its availability. Dense scrub and/or trees was the most selected habitat for nesting. This study gives us greater understanding as to how hedgehog taxa are adapted to their environment and therefore how they may be conserved, for example, the recent increase of “lower” level human activities, including irrigated farms and food waste, in harsh arid environments may have influenced the space use by Ethiopian hedgehogs.
Inference of Large-scale Time-delayed Gene Regulatory Network with Parallel MapReduce Cloud Platform
Authors: Yang Bin , Bao Wenzheng , Huang De-Shuang , Chen Yuehui
Published: December 2018

Inference of gene regulatory network (GRN) is crucial to understand intracellular physiological activity and function of biology. The identification of large-scale GRN has been a difficult and hot topic of system biology in recent years. In order to reduce the computation load for large-scale GRN identification, a parallel algorithm based on restricted gene expression programming (RGEP), namely MPRGEP, is proposed to infer instantaneous and time-delayed regulatory relationships between transcription factors and target genes. In MPRGEP, the structure and parameters of time-delayed S-system (TDSS) model are encoded into one chromosome. An original hybrid optimization approach based on genetic algorithm (GA) and gene expression programming (GEP) is proposed to optimize TDSS model with MapReduce framework. Time-delayed GRNs (TDGRN) with hundreds of genes are utilized to test the performance of MPRGEP. The experiment results reveal that MPRGEP could infer more accurately gene regulatory network than other state-of-art methods, and obtain the convincing speedup.

Structural insights into the molecular mechanism underlying Sirt5-catalyzed desuccinylation of histone peptides
Authors: Hang Tianrong , Chen Wanbiao , Wu Minhao , Zhan Li , Wang Chengliang , Jia Nan , Zhang Xuan , Zang Jianye
Published: December 2018

Histone modification is a ubiquitous regulatory mechanism involved in a variety of biological processes, including gene expression, DNA damage repair, cell differentiation, and ontogenesis. Succinylation sites on histones have been identified and may have functional consequences. Here, we demonstrate that human sirtuin 5 (Sirt5) catalyzes the sequence-selective desuccinylation of numerous histone succinyl sites. Structural studies of Sirt5 in complex with four succinyl peptides indicate an essential role for the conserved main chain hydrogen bonds formed by the succinyl lysine (0), +1, and +3 sites for substrate-enzyme recognition. Furthermore, biochemical assays reveal that the proline residue at the +1 site of the histone succinylation substrate is unfavorable for Sirt5 interaction. Our findings illustrate the molecular mechanism underlying the sequence-selective desuccinylase activity of Sirt5 and provide insights for further studies of the biological functions associated with histone succinylation and Sirt5.
Assessment of DC offset in fault current signal for accurate phasor estimation considering current transformer response
Authors: Achlerkar Pankaj D. , Panigrahi Bijaya Ketan
Published: December 2018

This study demonstrates the accurate signal model to be used for fault generated instantaneous current signals containing decaying DC offset by considering initial loading conditions and response of obvious non‐ideal current transformer (CT). The issue of CT core saturation and its impact on signal is evaluated. The comparative performance of existing DC offset estimation methods with modified DC part is discussed. Required modifications in existing least error square based estimation algorithms are proposed. The modified DC signal model is useful for applications such as more accurate phasor estimation, distance relaying and fault locations. Simulation studies are carried out in MATLAB/Simulink to demonstrate accuracy achieved by consideration of the proposed signal model.
Multiply imaged time-varying sources behind galaxy clusters
Authors: Wagner Jenny , Liesenborgs Jori , Eichler David
Published: December 2018

With upcoming (continuum) surveys of high-resolution radio telescopes, detection rates of fast radio bursts (FRBs) might approach 105 per sky per day by future extremely large observatories, such as the possible extension of the Square Kilometer Array (SKA) to a phase-2 array. Depending on the redshift distribution of FRBs and using the repeating FRB121102 as a model, we calculate a detection rate of multiply imaged FRBs with their multiply imaged hosts caused by the distribution of galaxy-cluster-scale gravitational lenses of the order of 10−4 per square degree per year for a minimum total flux of the host of 10 μJy at 1.4 GHz for SKA phase 2. Our comparison of estimated detection rates for quasars (QSOs), supernovae (SNe), gamma ray bursts (GRBs), and FRBs shows that multiple images of FRBs could be more numerous than those of GRBs and SNe and as numerous as multiple images of QSOs. Time delays between the multiple images of an FRB break degeneracies in model-based and model-independent lens reconstructions as other time-varying sources do, yet without a microlensing bias, as FRBs are more point-like and have shorter duration times. We estimate the relative imprecision of FRB time-delay measurements to be 10−10 for time delays on the order of 100 days for galaxy-cluster-scale lenses, yielding more precise (local) lens properties than time delays from the other time-varying sources. Using the lens modelling software Grale, we show the increase in accuracy and precision of the reconstructed scaled surface mass density map of a simulated cluster-scale lens when adding time delays for one set of multiple images to the set of observational constraints.
Nonaxisymmetric models of galaxy velocity maps
Authors: Sylos Labini Francesco , Benhaiem David , Comerón Sébastien , López-Corredoira Martín
Published: December 2018

Galaxy velocity mapsoften show the typical pattern of a rotating disk, consistent with the dynamical model where emitters rotate in circular orbits around the galactic center. The simplest template used to fit these maps consists in the rotating disk model (RDM) where the amplitude of circular velocities is fixed by the observed velocity profile along the kinematic axis. A more sophisticated template is the rotating tilted-ring model (RTRM) that takes into account the presence of warps and allows a radius-dependent orientation of the kinematic axis. In both cases, axisymmetry is assumed and residuals between the observed and the model velocity fields are interpreted as noncircular motions. We show that if a galaxy is not axisymmetric, there is an intrinsic degeneracy between a rotational and a radial velocity field. We then introduce a new galaxy template, the radial ellipse model (REM), that is not axisymmetric and has a purely radial velocity field with an amplitude that is correlated with the major axis of the ellipse. We show that best fits to the observed two-dimensional velocity fields of 28 galaxies extracted from the THINGS sample with both the REM and the RDM give residuals with similar amplitudes, where the REM residuals trace nonradial motions. Best fits obtained with the RTRM, because of its larger number of free parameters, give the smallest residuals: however, we argue that this does not necessarily imply that the RTRM gives the most accurate representation of a galaxy velocity field. Instead, we show that this method is not able to disentangle between circular and radial motions for the case of nonaxisymmetric systems. We then discuss a refinement of the REM, able to describe the properties of a more heterogeneous velocity field where circular and radial motions are respectively predominant at small and large distances from the galaxy center. Finally, we consider the physical motivation of the REM, and discuss how the interpretation of galactic dynamics changes if one assumes that the main component of a galaxy velocity field is modeled as a RDM/RTRM or as a REM.
Mergers, tidal interactions, and mass exchange in a population of disc globular clusters
Authors: Mastrobuono-Battisti Alessandra , Khoperskov Sergey , Di Matteo Paola , Haywood Misha
Published: December 2018

Globular clusters (GCs), the oldest stellar systems observed in the Milky Way, have long been considered single stellar populations. As such, they provided an ideal laboratory to understand stellar dynamics and primordial star formation processes. However, during the last two decades, observations have unveiled their true, complex nature. Beside their pristine stars, GCs host one or more helium enriched and possibly younger stellar populations whose formation mechanism is still unknown. Even more puzzling is the existence of GCs showing star-by-star iron spreads. Using detailed N-body simulations we explore the hypothesis that these anomalies in metallicity could be the result of mutual stripping and mergers between a primordial population of disc GCs. In the first paper of this series we proved, both with analytical arguments and short-term N-body simulations, that disc GCs have larger fly-by and close-encounter rates with respect to halo clusters. These interactions lead to mass exchange and even mergers that form new GCs, possibly showing metallicity spreads. Here, by means of long-term direct N-body simulations, we provide predictions on the dynamical properties of GCs that have undergone these processes. The comparison of our predictions with currently available and future observational data could provide insights into the origin of GCs and the Milky Way build-up history as a whole.
Slow-then-rapid quenching as traced by tentative evidence for enhanced metallicities of cluster galaxies at z ∼ 0.2 in the slow quenching phase
Authors: Maier C. , Ziegler B. L. , Haines C. P. , Smith G. P.
Published: December 2018

Aims. As large-scale structures in the Universe develop with time, environmental effects become more and more important as a star formation quenching mechanism. Since the effects of environmental quenching are more pronounced in denser structures that form at later times, we seek to constrain environmental quenching processes using cluster galaxies at z <  0.3.

Methods. We explored seven clusters from the Local Cluster Substructure Survey (LoCuSS) at 0.15 <  z <  0.26 with spectra of 1965 cluster members in a mass-complete sample from the ACReS (Arizona Cluster Redshift Survey) Hectospec survey covering a region that corresponds to about three virial radii for each cluster. We measured fluxes of [O II] λ 3727, Hβ, [O III] λ 5007, Hα, and [N II] λ 6584 emission lines of cluster members, enabling us to unambiguously derive O/H gas metallicities. We also measured star formation rates (SFRs) from extinction-corrected Hα fluxes. We compared our cluster galaxy sample with a field sample of 705 galaxies at similar redshifts observed with Hectospec as part of the same survey.

Results. We find that star-forming cluster and field galaxies show similar median specific SFRs in a given mass bin of 1 − 3.2 × 1010 M⊙ and 3.2 − 10 × 1010 M⊙, respectively. But their O/H values are displaced, in the lower mass bin, to higher values (significance 2.4σ) at projected radii of R <  R200 compared with galaxies at larger radii and in the field. The comparison with metallicity-SFR-mass model predictions with inflowing gas indicates a slow-quenching scenario in which strangulation is initiated when galaxies pass R ∼ R200 by stopping the inflow of gas. We find tentative evidence that the metallicities of cluster members inside R200 are thereby increasing, but their SFRs are hardly affected for a period of time because these galaxies consume available disk gas. We use the observed fraction of star-forming cluster galaxies as a function of clustercentric radius compared to predictions from the Millennium simulation to constrain quenching timescales to be 1−2 Gyr, which is defined as the time between the moment the galaxy passes R200 until complete quenching of star formation. This is consistent with a slow-then-rapid quenching scenario. Slow quenching (strangulation) starts when the gas inflow is stopped when the galaxy passes R200 with a phase in which cluster galaxies are still star forming, but they show elevated metallicities tracing the ongoing quenching. This phase lasts for 1−2 Gyr, and meanwhile the galaxies travel to denser inner regions of the cluster. This is followed by a “rapid” phase, i.e., a rapid complete quenching of star formation due to the increasing ram pressure toward the cluster center that can also strip the cold gas in massive galaxies.

Methyl mercaptan (also known as methanethiol), CH3SH, has been found in the warm and dense parts of high- as well as low- mass star-forming regions. The aim of the present study is to obtain accurate spectroscopic parameters of the S-deuterated methyl mercaptan CH3SD to facilitate astronomical observations by radio telescope arrays at (sub)millimeter wavelengths. We have measured the rotational spectrum associated with the large-amplitude internal rotation of the methyl group of methyl mercaptan using an isotopically enriched sample in the 150−510 GHz frequency range using the Köln millimeter wave spectrometer. The analysis of the spectra has been performed up to the second excited torsional state. We present modeling results of these data with the RAM36 program. CH3SD was searched for, but not detected, in data from the Atacama Large Millimeter/submillimeter Array (ALMA) Protostellar Interferometric Line Survey (PILS) of the deeply embedded protostar IRAS 16293−2422. The derived upper limit corresponds to a degree of deuteration of at most ∼18%.

Authors: Kuśmierczak Sylvia , Makovský Martin
Published: December 2018

Problems of degradation are mainly solved in finished products, in a number of cases it is manifested during production. A great influence on the degradation processes of the products has the surface quality and surface finish. The article deals with the problem of blackening of steel, which has been treated with alkaline blackening. The throttle shaft made of automatic steel will be analyzed. Degradation was manifested by a change in surface quality after alkaline blackening. The methods of light and electron microscopy in combination with complex analysis of production flow and technology conditions were used for analysis. Based on the results of analyzes it was found that the degradation processes are closely related to the quality of preparation of the surface. Owing to the incorrect pretreatment of the surface, oxides occurred locally. At the sites of oxides, after alkaline blackening, the surface layer was peeled off, resulting in deterioration in the quality of the product.

Published: December 2018

Laser scanning is an essential method for monitoring of the operation of buildings or structures. It involves creating as-is BIM from point clouds obtained from laser scanning. In this article we present our workflow for the generation of information model from 3D point clouds of concrete tetrapod blocks on navigable structure C-1. Point cloud processing method for making informational model for long term monitoring is described. As a result of the research BIM model with each tetrapod was created for deformational monitoring in the comparison with next year model. Finally, we identify and discuss technology gaps that need to be addressed in future research.

Most of the urban housing stock in Latvia as well as in major part of EU cities is apartment multi-storey buildings, most of which have a connection to centralized hot tap water systems. Also, such buildings as dormitories, university campuses, sporting facilities, mostly are connected to the centralized hot tap water systems. The hot tap water systems can have different optional technical solutions, such as recirculation loop, bath towels warmers, etc. All these options affect calculation’s specifics of the systems. The main challenge for designers is to make correct estimation of hydraulic losses, definition of necessary water flow rate and to choose such technical equipment as circulation pumps, balancing valves and circulation water flow. The main parameters directly affecting the sizing of hot tap water system are the number of inhabitants, designed water consumption, consumption uncertainty coefficient, building’s specifics etc. This study is based on the hot water consumption analysis in building were online monitoring system was installed.

Published: December 2018

The advanced energyand resource saving technologies for purification of industrial waste waters from the food production include both anaerobic biotechnologies, and the combined ones, which include anaerobic and aerobic purification steps. They possess such advantages as economic efficiency, high purification efficiency, minimal formation of excess sludge and ability to obtain alternative energy carrier - biogas. The aim of this investigation was to perform optimization of the process of anaerobic-aerobic biological purification of wastewaters from the milk treatment enterprise. During our investigation we have studied relations between the efficiency of the process of anaerobic-aerobic biological purification of wastewaters of the milk treatment enterprise and specific organic load. We investigated influence of the spatial separation of the anaerobic step of purification with directed succession of the microbial community, which performs the sequence of destruction of the organic compound on the process efficiency. It was shown, that the preliminary anaerobic purification of wastewaters from the milk treatment enterprise allows one to significantly reduce organic load at the aerobic stage of the purification facilities and remove up to 85% of the organic compound. With increase of the specific organic load from 1.4 up to 2.8 kg COD·m -3·days-1 we see a drastic improvement of the efficiency characteristics both for anaerobic and aerobic stages. The redox-potential of the fermentation medium depends on the metabolitic activity of the microbial community and might be used as an efficiency characteristics for destruction of the organic compound at the anaerobic stage, and as an indicator for the oxygen saturation of the medium at the aerobic stage of purification.

Screening in der Physiotherapie
Authors: Klein Patrick , Rottler Edit , von Wietersheim Jörn
Published: December 2018

Hintergrund Die richtige Diagnosestellung und daraus eine Behandlung ableiten, gehören zu den erforderlichen Grundfähigkeiten von Physiotherapeuten. Unklar ist, ob die unterschiedlichen Ausbildungsformen in Deutschland diese Qualifikationen auch hinreichend gut vermitteln und sich die Absolventen in ihren Leistungen unterscheiden.

Ziel Ziel dieser Fragebogenuntersuchung war es herauszufinden, inwieweit sich Teilnehmer einer physiotherapeutischen Ausbildung oder Studium in Deutschland und den Niederlanden bei vorgegebenen Fallvignetten für die richtige Diagnose und das richtige Prozedere entscheiden.

Methode Der Fragebogen nach Jette et al. 1 mit 12 Fallbeispielen wurde an Auszubildende und Studierende der Physiotherapie im letzten Ausbildungs- bzw. Studienjahr geschickt. Insgesamt nahmen 428 Auszubildende und Studierende aus Deutschland und 51 aus den Niederlanden an der Studie teil. Bei jeder Fallschilderung mussten sie sich für eine rein physiotherapeutische, medizinische oder gemischte Intervention entscheiden.

Ergebnisse Durchschnittlich 75 % der Teilnehmer entschieden sich für das richtige Prozedere. In Deutschland gaben Studierende eine signifikant höhere Anzahl richtiger Antworten im Vergleich zu den Auszubildenden. Im deutsch-niederländischen Vergleich waren die niederländischen Studierenden signifikant besser. Deutsche Auszubildende und Studierende wiesen vor allem bei medizinisch kritischen Beschwerdebildern schlechtere Ergebnisse auf.

Schlussfolgerungen In der Ausbildung und im Studium sollte die Vermittlung von Screening-Kenntnissen, besonders in Bezug auf medizinisch kritische Beschwerdebilder (Red Flags) verbessert werden.
The Efficacy of Tiapride and Carbamazepine Combination Therapy in Reducing Alcohol Withdrawal Symptoms: A Systematic Review and Meta-Analysis
Authors: Latifi Sahar , Messer Thomas
Published: December 2018

The combination of tiapride (TIA) and carbamazepine (CBZ) as an alternative treatment option to benzodiazepines and clomethiazole has been investigated by several investigations. We performed a systematic review and meta-analysis to further explore the efficacy of this combination in order to render more definite answers whether this combination can be recommendable in the clinical practice. We systematically searched electronic databases including PubMed (MEDLINE), EMBASE, OVID, Cochrane, Google Scholar, and Scopus for human studies. Statistical homogeneity was checked by χ2 test and I2 using Cochran heterogeneity statistic. Our analysis showed a significant efficacy of the combination of TIA and CBZ in reducing alcohol withdrawal syndrome (AWS) (p<0.0001, z-value: 4.07). The cumulative analysis illustrated that the favorable efficacy of this combination therapy has been consistent over time. Our study shows that the combination of TIA/CBZ is an effective treatment in management of AWS in patients with alcohol abstinence. However, the safety of this combination could not be proven, so we recommend its prescription after an informed consent.

Prescription Medication Misuse
Authors: Hill Jeoffrey , Alford Daniel
Published: December 2018

In the United States, there is a prescription medication misuse crisis including increases in unintentional drug overdose deaths, medications obtained on the illicit market (i.e., diversion), and in the number of individuals seeking treatment for addiction to prescription medications. Neurologists manage patients suffering from conditions (e.g., pain, seizures, spasticity) where the prescriptions of medications with misuse potential are indicated. It is therefore imperative that neurologists understand which medications are liable to misuse and institute strategies to minimize the harm associated with these medications. The authors review the most common medications prescribed by neurologist with misuse potential, and briefly discuss the behaviors that are suggestive of medication misuse and tools for monitoring patients to minimize medication-related harm from misuse.
