Authors: Gruhne Michael S. , Lommel Marcus , Wurzenberger Maximilian H. H. , Szimhardt Norbert , Klapötke Thomas M. , Stierstorfer Jörg 
Published: October 2019

AbstractSafety, performance, cost efficient synthesis and toxicity are the most important aspects of modern explosives. Sensitivity measurements are performed in accordance with different protocols all around the world. Sometimes the BAM drop hammer does not accurately reflect the sensitivity of an energetic material, in particular the sensitivity of primary explosives. Therefore, we present here preliminary results obtained using the novel ball drop tester (BIT‐132), manufactured by OZM research, following MIL‐STD‐1751 A (method 1016). The ball drop impact sensitivity tester is a device in which a free‐falling steel ball is dropped onto an unconfined sample, and is expected to produce more realistic results than the currently commonly used BAM method. The results obtained using the probit analysis were compared to those from the BAM drop hammer and friction tester. The following sensitive explosives were investigated: HMTD, TATP, TAT, Tetrazene, MTX‐1, KDNBF, KDNP, K2DNABT, Lead Styphnate Monohydrate, DBX‐1, Nickel(II) Hydrazine Nitrate, Silver Acetylide, AgN3, Pb(N3)2 RD‐1333, AgCNO, and Hg(CNO)2.
Design structure matrix‐based modularization approach for complex systems with multiple design constraints
Authors: Sinha Kaushik , Han Seok‐Youn , Suh Eun Suk 
Published: October 2019

AbstractDesigning a complex system generally requires its decomposition into smaller modular constituents for the ease of design, integration, operation, and future upgrades. Typically, system decomposition analysis is conducted using an abstract system model during the initial system design stage. The design structure matrix (DSM) has been a popular tool for abstract system modeling. In the DSM, systems are modeled and decomposed into modular configurations using published clustering algorithms. In this paper, we present a novel approach for system architecture decomposition and modularization based on the DSM, which can incorporate multiple design constraints into clustering algorithms. Two clustering algorithms are modified to accommodate the system design constraints. The modified algorithms are used to decompose a static inverter (SIV) of an electrical train into modular configurations that include various design constraints. Finally, the results and analysis of the SIV modularization using new modified clustering algorithms are presented.
Causal propagation of constraints in bimetric relativity in standard 3+1 form
Authors: Kocic Mikica 
Published: October 2019

AbstractThe goal of this work was to investigate the propagation of the constraints in the ghost-free bimetric theory where the evolution equations are in standard 3+1 form. It is established that the constraints evolve according to a first-order symmetric hyperbolic system whose characteristic cone consists of the null cones of the two metrics. Consequently, the constraint evolution equations are well-posed, and the constraints stably propagate.
Elementary Polynomial Identities Involving $$\varvec{q}$$-Trinomial Coefficients
Authors: Berkovich Alexander , Uncu Ali Kemal 
Published: October 2019

Abstract
We use the q-binomial theorem to prove three new polynomial identities involving q-trinomial coefficients. We then use summation formulas for the q-trinomial coefficients to convert our identities into another set of three polynomial identities, which imply Capparelli’s partition theorems when the degree of the polynomial tends to infinity. This way we also obtain an interesting new result for the sum of the Capparelli’s products. We finish this paper by proposing an infinite hierarchy of polynomial identities.

Zusammenfassung
Eine pathologische Druckerhöhung im pulmonalen Gefäßsystem (pulmonale Hypertonie, PH) wurde bisher definiert durch einen invasiv gemessenen mittleren pulmonalarteriellen Druck (mPAP) ≥25 mm Hg in Ruhe. Auf dem 6th World Symposium on Pulmonary Hypertension (WSPH) in Nizza 2018 wurde eine neue Definition der PH vorgeschlagen, die die Senkung der Obergrenze des normalen mPAP von 24 auf 20 mm Hg beinhaltet.
Obwohl keine Evidenz aus pädiatrischen Studien hierfür vorliegt, wurde diese neue PH-Definition (mPAP >20 mm Hg) aus Gründen der Einheitlichkeit auch von der pädiatrischen „Task Force“ des WSPH 2018 übernommen.
Die vorliegende Stellungnahme der Arbeitsgemeinschaft Pulmonale Hypertonie (AGPH) der Deutschen Gesellschaft für Pädiatrische Kardiologie und angeborene Herzfehler e. V. (DGPK) erläutert die zugrunde liegende Rationale und mögliche Konsequenzen dieser Definitionsänderung. Insbesondere stellt sie klar, dass diese Änderung der Definition aktuell keinen Einfluss auf die Verschreibung von Medikamenten zur gezielten spezifischen Therapie der pulmonalarteriellen Hypertonie hat.
The magic carpet: an arbitrary spectrum wave maker for internal waves
Authors: Dobra Thomas E. , Lawrie Andrew G. W. , Dalziel Stuart B. 
Published: October 2019

Abstract
We present a novel apparatus for generating internal waves of arbitrary size and shape, including both phase-locked and propagating waves. It is an actively driven, flexible “magic carpet” in the base of a tank. Our wave maker is computer-controlled to enable easy configuration. The actuation of a smooth, flexible surface produces clean waveforms with a predictable spectrum, for which we derive a theoretical model. We demonstrate the versatility of our wave maker through an experimental study of linear and nonlinear, isolated, and combined internal waves, including some that are sufficiently nonlinear to break remote from their source.

Published: October 2019

Abstract

Purpose
This study was to evaluate clinical outcomes using a patient-oriented test that scores health-related quality of life (HRQOL) for patients after minimally invasive surgery using microendoscopic discectomy (MED) for lumbar disc hernia. Few studies regarding MED in terms of disease-specific quality of life measures using Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) have been published.

Methods
Retrospective analysis of the surgical and clinical outcomes with regard to reducing pain and improving the functional status for 31 patients who underwent MED for lumbar disc hernia was conducted. These patients were evaluated at 3-year follow-up. The evaluations were based on a visual analogue scale (VAS), the Japanese Orthopaedic Association (JOA) scoring system, and the JOABPEQ, which is an objective, patient-oriented test that assesses HRQOL in patients with lumbar disorders.

Results
A low rate of improvement was seen only in mental health until 1 year, the low rate of improvement in mental health and was independently correlated with body mass index (BMI), pre-operative scores on the Brief Scale for Psychiatric problems in Orthopaedic Patients (BS-POP), and scores on the BS-POP at 12 months post-operatively.

Conclusions
All categories of VAS, JOA scores, and all domains of JOABPEQ were significantly higher over 3 years than those obtained pre-operatively. But only mental health domain showed mild improvement until 1 year. Moreover, BMI showed a negative correlation with improvements in the mental health domain post-operatively. As patients may be mentally exhausted from lumbar disc herniation, pre-operative mental health may be improved by surgical treatment.
The company you keep: health behavior among work peers
Authors: Pruckner Gerald J. , Schober Thomas , Zocher Katrin 
Published: October 2019

AbstractThere is widespread agreement that behavior crucially influences one’s health. However, little is known about what actually determines health-related behavior. We explore the impact of the place where many people spend most of their time, at work, and analyze whether an individual’s decision to participate in health screening is related to the observed behavior of peers at work. We use linked employer–employee data and exploit the transitions of workers to new jobs. We find that the health behavior of co-workers highly correlated. A comparison of individuals moving into new firms shows that participation in general health checks, mammography screening, and prostate-specific antigen tests increases with the share of work peers attending these screenings. To differentiate between peer effects and common influences at the workplace, we further separate the peer groups within firms and show that workers with similar characteristics tend to have a stronger effect on individual screening participation.
Predicting growth and habitat responses of Ginkgo biloba L. to climate change
Authors: Guo Ying , Lu Yue , El-Kassaby Yousry A. , Feng Lei , Wang Guibing , Wang Tongli 
Published: October 2019

Abstract
Key message
We developed a climatic response function using 20-year tree height observed from 45Ginkgo bilobaplantations in China and used it to predict the growth and habitat responses to anticipated climate change. We projected northward and upward shifts in the species habitat and productive areas, but a dramatic contraction of the species distribution is unlikely to occur at least during the present century.

Context
Ginkgo biloba is the only living species in the division Ginkgophyta. The species exists in small natural populations in southeastern China but is cultivated across China and the world. The species’ future under climate change is of concern.

Aims
This study was initiated to model the species’ growth response to climate change and to predict its range of suitable habitat under future climates.

Methods
Using height data from 45 20 years old plantations growing under a wide range of climatic conditions across China, we developed univariate and bivariate climatic response functions to identify the climate requirements of the species.

Results
According to the amount of variance explained (> 70%) and the high level of agreement (> 99%) with independent species occurrence coordinates, the developed climate response function was highly accurate and credible. Projections for future periods (2011–2040, 2041–2070, and 2071–2100) under the Representative Concentration Pathway 4.5 (RCP4.5) scenario indicated that the areas of potential suitable habitat would increase (25–67 million hectares). It would also be associated with northward (0.21–0.62° in latitude) and elevational (24–75 m) shifts.

Conclusion
Global climate change is projected to increase the area of potential suitable habitats for Ginkgo and shift its spatial distributions northward and upward.
Proteomic analysis of black poplar (Populus nigra L.) seed storability
Authors: Pawłowski Tomasz A. , Klupczyńska Ewelina A. , Staszak Aleksandra M. , Suszka Jan 
Published: October 2019

Abstract
Key message

Adequate storability of black poplar (Populus nigraL.) seeds at temperatures below 0 °C was associated with preservation of proteins of energy and carbohydrate metabolism, protein turnover, and proteins maintaining long-term stability of dehydrated tissue.

Context
Understanding seed storability is a key factor for effective seed preservation and conservation. Black poplar is an endangered tree species and its seed loses rapidly viability during storage.

Aims
The aim of this study was to determine, and functionally characterise, the proteins associated with storability of black poplar seeds.

Methods
Dried seeds (7.1% MC) were stored at 3 °C, − 3 °C, − 20 °C, and − 196 °C, for a period of 12 and 24 months. Proteins were extracted and separated according to their isoelectric point (pI) and mass using 2-dimensional electrophoresis. Proteins that varied in abundance for temperature and time of storage were identified by mass spectrometry.

Results
A germination test showed that seeds remained viable at − 3, − 20, and − 196 °C. Storage at 3 °C caused loss of seed viability. This loss in seed vigour was related to the largest changes in protein abundance. As storage temperature decreased, a smaller number of proteins displayed changed abundance.

Conclusion
Good storability of black poplar seeds under freezing conditions may be associated with the following: an inhibition of synthesis of energy and carbohydrate metabolism and protein turnover proteins, LEA proteins that maintain long-term stability of dehydrated tissue, GDSL esterases/lipases that inhibit hydrolysing activity, and by chaperonins that protect protein functionality. Storage conditions influence the preservation of protein function that governs seed viability.

Published: October 2019

AbstractDisasters exact a heavy toll globally. However, the degree to which we can accurately quantify their impact, in particular mortality, remains challenging. It is critical to ensure that disaster data reliably reflects the scale, type, and distribution of disaster impacts given the role of data in: (1) risk assessments; (2) developing disaster risk management programs; (3) determining the resources for response to emergencies; (4) the types of action undertaken in planning for prevention and preparedness; and (5) identifying research gaps. The Sendai Framework for Disaster Risk Reduction 2015–2030s seven global disaster-impact reduction targets represent the first international attempt to systematically measure the effectiveness of disaster-impact reduction as a means of better informing policy with evidence. Target A of the Sendai Framework aims to “substantially reduce global disaster mortality by 2030, aiming to lower the average per 100,000 global mortality rate in the decade 2020–2030 compared to the period 2005–2015.” This article provides an overview of the complexities associated with defining, reporting, and interpreting disaster mortality data used for gauging success in meeting Target A, acknowledging different challenges for different types of hazard events and subsequent disasters. It concludes with suggestions of how to address these challenges to inform the public health utility of monitoring through the Sendai Framework.
Georeferencing of an Unmanned Aerial System by Means of an Iterated Extended Kalman Filter Using a 3D City Model
Authors: Bureick Johannes , Vogel Sören , Neumann Ingo , Unger Jakob , Alkhatib Hamza 
Published: October 2019

Abstract
In engineering geodesy, the technical progress leads to various kinds of multi-sensor systems (MSS) capturing the environment. Multi-sensor systems, especially those mounted on unmanned aerial vehicles, subsequently called unmanned aerial system (UAS), have emerged in the past decade. Georeferencing for MSS and UAS is an indispensable task to obtain further products of the data captured. Georeferencing comprises at least the determination of three translations and three rotations. The availability and accuracy of Global Navigation Satellite System (GNSS) receivers, inertial measurement units, or other sensors for georeferencing is not or not constantly given in urban scenarios. Therefore, we utilize UAS-based laser scanner measurements on building facades. The building latter are modeled as planes in a three-dimensional city model. We determine the trajectory of the UAS by combining the laser scanner measurements with the plane parameters. The resulting implicit measurement equations and nonlinear equality constraints are covered within an iterated extended Kalman filter (IEKF). We developed a software simulation for testing the IEKF using different scenarios to evaluate the functionality, performance, strengths, and remaining challenges of the IEKF implemented.

Published: October 2019

Abstract
One of the chief goals of periodontal plastic surgery is establishment of ideal pink esthetics through the reconstruction of gingival recessions. A gold standard treatment approach for coverage of gingival recession with predictable esthetic outcomes is the transplantation of autogenous soft tissue grafts. Various surgical techniques can be used in combination with autogenous soft tissue grafts for gingival recession coverage.

Published: October 2019

On May 30, 2019, the Agreement Establishing the African Continental Free Trade Area (AfCFTA) entered into force for the twenty-four countries that had deposited their instruments of ratification. When the remaining thirty-one member states of the African Union ratify it, the AfCFTA will cover a market of 1.2 billion people and a gross domestic product (GDP) of $2.5 trillion. That would make it the world's largest trade agreement since the World Trade Organization (WTO).
Incidentally detected small fistula flows in pulmonary artery by colour Doppler: echocardiographic findings and follow-up results
Authors: Atik Sezen Ugan , Saltik Irfan Levent 
Published: October 2019

AbstractAbnormal small fistulous flows in the pulmonary artery were detected on routine transthoracic echocardiography in asymptomatic patients by colour Doppler echocardiography. The most likely diagnosis is small coronary artery-pulmonary artery fistulas. We evaluated the clinical, echocardiographic, and follow-up findings of 101 patients. The mean age at first echocardiographic evaluation was 4.3 ± 4.2 years. In 79 (78.2%) of the patients, fistula flow in the pulmonary artery was diagnosed at the first presentation and the remaining 22 patients (21.8%) were diagnosed between the 2nd and 10th examination. The echocardiography indication was cardiac murmur in 42 (41.6%), routine cardiac control in 30 (29.7%), additional CHD in 14 (13.8%), non-specific chest pain in 11 (10.9%), suspicion of inflammatory heart disease in 2 (2%), and syncope in 2 (2%) patients. In 70 (69.3%) patients, fistulous flow was located in the anterior aspect of the main pulmonary artery, in 23 (22.8%) patients on the aortic side of the pulmonary artery and in 8 (7.9%) patients on the right pulmonary artery. Additional cardiac anomalies were ventricular septal defect in 8, patent ductus arteriosus in 6, atrial septal defect in 5, mitral valve prolapse in 4, coarctation of aorta in 4, bicuspid aortic valve in 3, and Kawasaki syndrome in 1 patient. Sixty-four patients (63.3%) were followed during a mean of 52.6 ± 43.7 months. Spontaneous closure was detected in only three patients; the others remained almost unchanged during the follow-up. Since the fistulas are thin and hemodynamically insignificant, echocardiography is an appropriate method to monitor these patients without performing any invasive diagnostic procedures for the fistula source.
Apical hypertrophic cardiomyopathy: an uncommon cause of exertional chest pain in children
Authors: Zhao Qu-ming , He Lan , Liu Fang 
Published: October 2019

AbstractApical hypertrophic cardiomyopathy is an uncommon morphologic variant of hypertrophic cardiomyopathy, which is rarely diagnosed in childhood. To date, very few cases of asymptomatic children younger than 18 years have been reported in the literature. To the best of our knowledge, this is the first case of paediatric apical hypertrophic cardiomyopathy presenting with exertional chest pain, with characteristic electrocardiographic, echocardiographic, MRI, and cardiac angiography findings.

Published: October 2019

AbstractObjective:To evaluate awareness of the Eat Well Campaign (EWC) among parents and assess perceptions about its effectiveness.Design:Post-campaign evaluation study with a cross-section of parents recruited through random digit dialling. Participants completed an online survey about EWC awareness, its perceived effectiveness among parents and their meal planning practices (attitudes, behaviours and self-efficacy).Setting:A federal mass-media campaign disseminated by Health Canada (2013–2014) to promote meal planning to Canadian parents.Participants:Parents (n 964) of children aged 2–12 years from all Provinces and Territories.Results:Of respondents, 41 % (390/964) were aware of the campaign; Quebec City and rural Quebec had the highest rates of awareness, whereas Vancouver, Winnipeg and Toronto had the lowest. Awareness was greater among parents with lower income, basic education and French-speakers. Campaign intensity was significantly associated with greater odds of reporting positive attitudes towards the EWC and meal planning (P < 0·05). Campaign awareness was significantly associated with greater odds of believing that meal planning helps maintain a healthy diet (OR = 1·68, 95 % CI 1·03, 2·74) and planning meals (OR = 1·66, 95 % CI 1·03, 2·54), but not self-efficacy, in adjusted models.Conclusions:The present study is the first to evaluate an initiative that promoted meal planning with mass media. The EWC demonstrated evidence of success in terms of equitable access to a nutrition initiative by reaching lower-income and less-educated parents. Understanding behavioural factors among different segments of the population will be important to target appropriate audiences and develop tailored interventions that support healthy eating practices.
The merger debris of dwarf galaxies in the local stellar halo
Authors: Du Cuihua , Li Hefan , Newberg Heidi Jo 
Published: October 2019

AbstractBased on the second Gaia data release and spectroscopy from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data, we identified 23,582 halo stars kinematically. The halo streams in the solar neighborhood could be detected in the space of energy and angular momentum. We reshuffle the velocities of these stars to determine the significance of the substructure. Finally, we find 14 statistically significant substructures and several substructures are not reported by previous works. These structures may be the debris of dwarf galaxies accretion event and their dynamical and chemical information can help to understand the history of the Galaxy.
