Published: August 2021

China is one of the countries with the most serious natural disasters in the world. Hidden dangers and risks of all kinds of accidents are intertwined and superimposed, and the factors affecting public safety are increasing. It is urgent to strengthen the construction of emergency medical rescue capacity. During the nineteenth collective learning of the Central Political Bureau, general secretary Xi Jinping stressed that we should strengthen the capacity building of aviation emergency rescue and improve the airspace guarantee mechanism for emergency rescue. As the most important aerial medical evacuation platform, helicopter has the advantages of fast response, strong mobility, wide rescue range, direct arrival at the first line of treatment, etc. it has become an important means of modern rescue, and also the only way to open life treatment in case of land damage. From the international experience, the helicopter emergency medical system established by most developed countries plays an important role in disaster relief and anti‐terrorism. China has a large population, complex terrain and uneven regional development. In case of disasters, the casualties are often more severe and the demand for treatment is more urgent. It is urgent to establish an aviation medical emergency rescue system suitable for the national conditions and with helicopters as the main carrier, and accelerate the research and development of key technical equipment.In recent years, more and more people realize the necessity and benefits of the application of interactive technology for aviation medical simulation training in major events and disasters. Interaction refers to the transmission and exchange of intelligence, data, data and technical knowledge in all aspects of nature and society. From the perspective of information theory, local chronicles are a tangible text information carrier, which collects all kinds of information in a certain region. Interactive technology is to use certain means to achieve the purpose of interaction, and gradually enter the era of multi field application! In thefield of aviation medical rescue, it is in urgent need of penetration and integration.This paper mainly develops an AR emergency rescue process training system. Through the creation of data sets, action recognition based on computer vision and deep learning, the selection of recognition model and action capture, the action is recognized based on AR, and then 22 joint points of human hand and upper arm skeleton are taken to label the data space position. Through the above learning results, we can get the real‐time hand recognition based on depth information Upper arm skeleton output. Neural network is used to recognize human skeleton action. The skeleton information coordinates are imported into RNN neural network for deep learning. Finally, based on the complementarity of CNN and LSTM, combined with the idea of dual stream structure network, the action recognition is carried out.

Published: August 2021

AbstractThe N‐doped porous carbon (NPC) /carbon micro‐nanotubes (CMNT) /NixCoyOz nanosheets with rich mesopores and 1.37 wt% nitrogen doping are successfully synthesized by a pyrolysis‐ionization‐precipitation combination process, using coal‐based polyaniline and nickelocene as original materials. Therein, most of the CMNT are upright CMTs and worm‐like curved CNTs, and a few are bamboo‐like tubes or carbon nanofibers. Moreover, many flower‐like aggregates assembled by spinel NiCo2O4 nanosheets are anchored on the surface of the NPC and CMNT. The NPC/CMNT/NixCoyOz exhibits a high specific capacitance and cycling stability, attributed to the large BET specific surface area (485 m2/g), suitable BET average pore size (2.3 nm), good hydrophilicity and wettability, and synergistic effects among three components. The assembled NPC/CMNT/NixCoyOz//AC asymmetric supercapacitor also demonstres a high specific capacitance of 120 F g−1 at a current density of 1 A g−1 and a high energy density of 16.7 Wh kg−1 at a power density of 500 W kg−1.
Six-point functions and collisions in the black hole interior
Authors: Haehl Felix M. , Streicher Alexandre , Zhao Ying 
Published: August 2021

Abstract
In the eternal AdS black hole geometry, we consider two signals sent from the boundaries into the black hole interior shared between the two asymptotic regions. We compute three different out-of-time-order six-point functions to quantify various properties of the collision of these signals behind the horizons: (i) We diagnose the strength of the collision by probing the two-signal state on a late time slice with boundary operators. (ii) We quantify two-sided operator growth, which provides a dual description of the signals meeting in the black hole interior, in terms of the quantum butterfly effect and quantum circuits. (iii) We consider an explicit coupling between the left and right CFTs to make the wormhole traversable and extract information about the collision product from behind the horizon. At a technical level, our results rely on the method of eikonal resummation to obtain the relevant gravitational contributions to Lorentzian six-point functions at all orders in the GN-expansion. We observe that such correlation functions display an intriguing factorization property. We corroborate these results with geodesic computations of six-point functions in two- and three-dimensional gravity.

Abstract
Objectives
We assessed possible myocardial involvement in previously cardiac healthy post-COVID patients referred for persisting symptoms with suspected myocarditis.

Background
Prior studies suggested myocardial inflammation in patients with coronavirus-induced disease 2019 (COVID-19). However, the prevalence of cardiac involvement among COVID patients varied between 1.4 and 78%.

Methods
A total of 56 post-COVID patients without previous heart diseases were included consecutively into this study. All patients had positive antibody titers against SARS-CoV-2. Patients were referred for persistent symptoms such as chest pain/discomfort, shortness of breath, or intolerance to activity. All patients underwent standardized cardiac assessment including electrocardiogram (ECG), cardiac biomarkers, echocardiography, and cardiac magnetic resonance (CMR).

Results
56 Patients (46 ± 12 years, 54% females) presented 71 ± 66 days after their COVID-19 disease. In most patients, the course of COVID-19 was mild, with hospital treatment being necessary in five (9%). At presentation, patients most often reported persistent fatigue (75%), chest pain (71%), and shortness of breath (66%). Acute myocarditis was confirmed by T1/T2-weighed CMR and elevated NTpro-BNP levels in a single patient (2%). Left ventricular ejection fraction was 56% in this patient. Additional eight patients (14%) showed suspicious CMR findings, including myocardial edema without fibrosis (n = 3), or non-ischemic myocardial injury suggesting previous inflammation (n = 5). However, myocarditis could ultimately not be confirmed according to 2018 Lake Louise criteria; ECG, echo and lab findings were inconspicuous in all eight patients.

Conclusions
Among 56 post-COVID patients with persistent thoracic complaints final diagnosis of myocarditis could be confirmed in a single patient using CMR.

Analyse der Kolbengruppenreibung und -schmierung von Ottomotoren – Die Bedeutung des Ölabstreifrings
Authors: Schäffer Julian , Wachtmeister Georg 
Published: August 2021

ZusammenfassungFür die Realisierung der in Paris definierten Klimaschutzziele wird die Optimierung des Verbrennungsmotors weiterhin eine tragende Rolle spielen. Sowohl für den Kleinmotor im Hybridantrieb als auch für den Großmotor in Nutzfahrzeugen und Baumaschinen hat eine Effizienzsteigerung höchste Priorität. Maßnahmen zur Reduktion der mechanischen Verluste werden typischerweise mit geschleppten Reibleistungsmessungen am Vollmotor (Strip-down Analyse) bewertet. Die Ergebnisse zeigen, dass bis zu 50 % der Gesamtverluste im tribologischen System Kolben/Zylinderlaufbahn entstehen. Zur Analyse der Kolbengruppenreibung wird eine kurbelwinkelbasierte Reibkraftmessung am Einzylindermotor eingesetzt, aus der sich der Reibmitteldruck als Maß der Effizienz ableiten lässt. Mit dem sogenannten Floating-Liner Motor wird zunächst bewertet, welche Wirkung mit der Tangentialkraftreduktion des Ölabstreifrings hinsichtlich Reibungsverluste erzielt werden kann. Da sich Reibung stets im Spannungsfeld mit Ölverbrauch befindet, wird zudem die Wirkung der reduzierten Tangentialkraft auf den Ölhaushalt der Kolbengruppe analysiert. Hierzu wurde ein Transparent-Aggregat entwickelt, das die Visualisierung der Schmierölströmung als auch eine Bewertung der Ölschichtdicken ermöglicht. Mit diesem kombinierten Ansatz können Maßnahmen gefunden werden, die zu einer Reduktion des CO2-Ausstoßes bei gleichbleibenden Ölemissionen führen. Letzteres gewinnt mit dem zukünftigen Einsatz synthetisch hergestellter Kraftstoffe (eFuels) zunehmend an Bedeutung, da diese nahezu partikelfrei verbrennen und somit der Öleintrag in den Brennraum als einzige Partikelquelle verbleibt.
Determination of the high-strain rate elastic modulus of printing resins using two different split Hopkinson pressure bars
Authors: Aghayan S. , Bieler S. , Weinberg K. 
Published: August 2021

AbstractThe usage of resin-based materials for 3D printing applications has been growing over the past decades. In this study, two types of resins, namely a MMA-based resin and an ABS-based tough resin, are subjected to compression tests on a split Hopkinson pressure bar to deduce their dynamic properties under high strain rate loading.Two Hopkinson bar setups are used, the first one is equipped with aluminum bars and the second one with PMMA bars. From the measured strain waves, elastic moduli at high strain rates are derived. Both setups lead to values of$E=3.4$E=3.4–3.8 GPa at a strain rate of about 250 s−1. Numerical simulations support the experiments. Moreover, considering the waves gained from the two different bar setups, PMMA bars appear to be well-suited for testing resin samples and are therefore recommended for such applications.
Taming conceptual wanderings: Wilson-Structuralism
Authors: De Benedetto Matteo 
Published: August 2021

AbstractMark Wilson presents a highly original account of conceptual behavior that challenges many received views about concepts in analytic philosophy. Few attempts have been made to rationally reconstruct Wilson’s framework of patches and facades within a precise semantic framework. I will show how a modified version of the structuralist framework offers a semantic reconstruction of scientific theories capable of modeling Wilson’s ideas about conceptual behavior. Specifically, I will argue that Theory-Elements and a modified version of Theory-Nets explicate respectively Wilson’s patches and facades. I will also demonstrate how several wandering phenomena described by Wilson can be adequately reconstructed within my framework.

ZusammenfassungDie Beiträge des Schwerpunkts „Interessenvertretung in der Kinder- und Jugendhilfe“ befassen sich mit den Möglichkeiten der Partizipation und Selbstorganisation, die Kindern und Jugendlichen in unterschiedlichen Feldern der Kinder- und Jugendhilfe eröffnet bzw. verwehrt sind. Obwohl solche Möglichkeiten durchaus eine rechtliche Verankerung haben, sind sie in der Praxis nur unzureichend umgesetzt. Wie die Beiträge verdeutlichen, liegen die Ursachen hierfür in Dilemmata, die nicht zuletzt in Strukturen der Kinder- und Jugendhilfe ihre Ursache haben. Aus fünf unterschiedlichen Perspektiven wird ein Einblick in jene strukturellen Dilemmata gegeben, die jeweils der Mitgestaltung junger Menschen im Hinblick auf ihre Lebensentwürfe und -umstände entgegenstehen; gleichzeitig werden Möglichkeiten deren produktiver Bearbeitung aufgezeigt.

Published: August 2021

AbstractPurpose of ReviewRobotic assistance systems for diagnosis and therapy have become technically mature and widely available. Thus, they play an increasingly important role in patient care. This paper provides an overview of the general concepts of robotically assisted surgical systems, briefly revisiting historical and current developments in the surgical robotics market and discussing current focus areas of research. Comprehensiveness cannot be achieved in this format, but besides the general overview, references to further readings and more comprehensive reviews with regard to particular aspects are given. Therefore, the work at hand is considered as an introductory paper into the topic and especially addresses investigators, researchers, medical device manufacturers, and clinicians, who are new to this field.Recent FindingsThe current research in Robotically Assisted Surgical Systems (RASS) increasingly uses established robotic platforms. To minimize the patient trauma while optimizing the dexterity of the surgeon, miniaturized instruments and semi-autonomous assistance functions are developed. To provide the surgeon with all necessary information in an adequate manner, novel imaging sensors as well as techniques for multimodal sensory feedback and augmented reality are investigated. The Surgical Data Science applies data management and processing approaches including machine learning on medical data to provide optimal, individualized and contextual support to the surgeon.SummaryRobotic systems will significantly influence future patient care. Since they must fulfill manifold medical, technical, regulatory and economic requirements, their development calls for a close, active and interdisciplinary cooperation between stakeholders from hospitals, industry and science.

Authors: Abate Semagn Mekonnen , Ahmed Siraj , Anbese Getachew Mergia , Basu Bivash 
Published: August 2021

ABSTRACT

Background:
Post-Dural Puncture Headache is the commonest complication of spinal anesthesia. Body of evidence revealed that Conservative management failed to show significant benefit and epidural needle and catheter techniques didn’t provide conclusive evidence. On the other hand, intrathecal injection of normal saline is a simple technique and cost-effective in a resource-limited setup but it is not well examined on its effectiveness and safety profiles.

Methods and materials:
After Obtaining Ethical clearance from IRB, 152 mothers scheduled for cesarean section under spinal anesthesia were allocated randomly into two groups. Data analysis was done with SPSS version 22. Descriptive statistics were run to see the overall distribution of the study subjects. Unpaired student’s T-test for continuous symmetric data and Mann-Whitney U test for non-normally distributed data were used. Categorical data were analyzed with Chi-square and fisher’s exact test where appropriate. A generalized estimating equation model was used to investigate the interaction of repeated measurements of NRS pain scores of PDPH.

Result:
The overall incidence of PDPH was 29.6% while the proportion of patients who experienced PDPH was the highest among patients with control as compared to intervention( 36.8% vs 22%) respectively. The GEE model revealed that the NRS pain score was 0.7, 0.4, and 0.2 unit higher at 12, 24, and 48 respectively in control as compared to the intervention

Conclusion:
prophylactic intrathecal normal saline could be an option in a resource-limited setup where the appropriate spinal needle is not accessible and management of moderate and severe PDPH is not feasible

Registration:
The protocol was registered prospectively in Clinical Trials.gov (NCT04393766).

AbstractRecent absorbed residue studies have confirmed that ceramic and shell containers were used for consuming Datura in precolumbian times. Until now, no one has identified what tools precolumbian people used to produce a concentrated hallucinogenic concoction. In this study, we used mass spectrometry to identify Datura residues (a flowering plant with hallucinogenic properties) in two late precolumbian composite bottles from the Central Arkansas River valley. Unlike the construction of most Mississippian bottles, the bottles in this study are unique because ceramic disks with a series of concentric perforations were incorporated in the bottles at the juncture of the bottle neck with the globular portion of the body. The organic residue analysis revealed Datura residues in both bottles. We argue that the internal clay disks served as strainers that allowed Datura producers to separate the hallucinogenic alkaloids from the Datura flower to produce a powerful liquid beverage.

AbstractOur objective was to quantify the cross-sectional associations between dietary fatty acid (DFA) patterns and cognitive function among Hispanic/Latino adults. This study included data from 8942 participants of the Hispanic Community Health Study/Study of Latinos, a population-based cohort study (weighted age 56·2 years and proportion female 55·2 %). The National Cancer Institute method was used to estimate dietary intake from two 24-h recalls. We derived DFA patterns using principal component analysis with twenty-six fatty acid and total plant and animal MUFA input variables. Global cognitive function was calculated as the average z-score of four neurocognitive tests. Survey linear regression models included multiple potential confounders such as age, sex, education, depressive symptoms, physical activity, energy intake and CVD. DFA patterns were characterised by the consumption of long-chain SFA, animal-based MUFA and trans-fatty acids (factor 1); short to medium-chain SFA (factor 2); very-long-chain n-3 PUFA (factor 3); very-long-chain SFA and plant-based MUFA and PUFA (factor 4). Factor 2 was associated with greater scores for global cognitive function (β = 0·037 (sd 0·012)) and the Digit Symbol Substitution (DSS) (β = 0·56 (sd 0·17)), Brief Spanish English Verbal Learning-Sum (B-SEVLT) (β = 0·23 (sd 0·11)) and B-SEVLT-Recall (β = 0·11 (sd 0·05)) tests (P < 0·05 for all). Factors 1 (β = 0·04 (sd 0·01)) and 4 (β = 0·70 (sd 0·18)) were associated with the DSS test (P < 0·05 for all). The consumption of short to medium-chain SFA may be associated with higher cognitive function among US-residing Hispanic/Latino adults. Prospective studies are necessary to confirm these findings.
Revolutionary legality and the Burkinabè insurrection
Authors: Brett Peter 
Published: August 2021

ABSTRACTCoup leaders often purport to restore constitutional order. During Burkina Faso's 2014 ‘insurrection', however, Blaise Compaoré's opponents advanced detailed (international) legal arguments that significantly constrained their subsequent conduct. Theirs was to be a legal revolution. This article situates this stance within Burkina Faso's distinctive history of urban protest, whilst emphasising under-analysed international sources for the insurrection. ‘Insurgent’ lawyers, it argues, used international instruments to reinvigorate longstanding activist attempts to reconcile constitutional rights with a language of popular justice promoted by the revolutionary regime of Thomas Sankara (1983–7). After the insurrection, however, their emphasis on legality was used by Compaoré's supporters to expose the transitional authorities’ double-standards. Meanwhile, insurgent lawyers working for the transition had to work hard to reconcile (international) legal justifications for the insurrection with the expedient politics needed to defend the new dispensation.
A web-based language learning environment: general architecture
Authors: Foucou Pierre-Yves , Kübler Natalie 
Published: August 2021

In this paper, we present the Web-based CALL environment (or WALL) which is currently being experimented with at the University of Paris 13 in the Computer Science Department of the Institut Universitaire de Technologie. Our environment is being developed to teach computer science (CS) English to CS French-speaking students, and will be extended to other languages for specific purposes such as, for example, English or French for banking, law, economics or medicine, where on-line resources are available.English, and more precisely CS English is, for our students, a necessary tool, and not an object of study. The learning activities must therefore stimulate the students' interest and reflection about language phenomena. Our pedagogical objective, relying on research acquisition (Wokusch 1997) consists in linking various texts together with other documents, such as different types of dictionaries or other types of texts, so that knowledge can be acquired using various appropriate contexts.Language teachers are not supposed to be experts in fields such as computer sciences or economics. We aim at helping them to make use of the authentic documents that are related to the subject area in which they teach English. As shown in Foucou and Kübler (1998) the wide range of resources available on the Web can be processed to obtain corpora, i.e. teaching material. Our Web-based environment therefore provides teachers with a series of tools which enable them to access information about the selected specialist subject, select appropriate specialised texts, produce various types of learning activities and evaluate students' progress.Commonly used textbooks Tor specialised English offer a wide range of learning activities, but they are based on documents that very quickly become obsolete, and that are sometimes widely modified. Moreover, they are not adaptable to the various levels of language of the students. From the students' point of view, working on obsolete texts that are either too easy or too difficult can quickly become demotivating, not to say boring.In the next section, we present the general architecture of the teaching/learning environment; the method of accessing and using it, for teachers as well as for students, is then described. The following section deals with the actual production of exercises and their limits. We conclude and present some possible research directions.
