CHINA'S FOREIGN POLICY TOWARDS MYANMAR: A ROLE MODEL IN INTERNATIONAL RELATIONS
Authors: Zreik Mohamad 
Published: March 2021

China has a large and professional diplomatic team spread all over the world. Chinese diplomacy mainly relies on soft power in its relations with international partners. Despite the unified outlines, Chinese foreign policy differs from one country to another, depending on the geographical location, the political system and the volume of trade exchange. Chinese foreign policy has gone through many stages, most notably the period of Mao Zedong who strictly applied the rules of socialism, and the period of Deng Xiaoping, known for its reform and openness policy, thus establishing a modern and more flexible Chinese system.
President Xi Jinping's term is an extension of Deng Xiaoping's rule of thumb, but with more openness to international partners and economic expansion, especially with the launch of the Belt and Road Initiative in 2013. This paper deals with China's foreign policy towards Myanmar, and refers to the development of bilateral relations and China's interest in a distinguished relationship with Myanmar. The research indicates the strategic factors that make China interested in developing the relationship with Myanmar.

Background: Many different methods are applied for radon mapping depending on the purpose of the map and the data that are available. In addition, the definitions of radon priority areas (RPA) in EU Member States, as requested in the new European EURATOM BSS (1), are diverse.
Objective: 1) Comparison of methods for mapping geogenic and indoor radon, 2) the possible transferability of a mapping method developed in one region to other regions and 3) the evaluation of the impact of different mapping methods on the delineation of RPAs.
Design: Different mapping methods and several RPA definitions were applied to the same data sets from six municipalities in Austria and Cantabria, Spain.
Results: Some mapping methods revealed a satisfying degree of agreement, but relevant differences were also observed. The chosen threshold for RPA classification has a major impact, depending on the level of radon concentration in the area. The resulting maps were compared regarding the spatial estimates and the delineation of RPAs.
Conclusions: Not every mapping method is suitable for every available data set. Data robustness and harmonisation are the main requirements, especially if the used data set is not designed for a specific technique. Different mapping methods often deliver similar results in RPA classification. The definition of thresholds for the classification and delineation of RPAs is a guidance factor in the mapping process and is as relevant as harmonising mapping methods depending on the radon levels in the area.
Laser-induced multiple points ignition test in Al/Ni exothermic reactive film for crack propagation control
Authors: Maekawa Kana , Kodama Kenta , Miyake Shugo , Namazu Takahiro 
Published: March 2021

Abstract
Al/Ni multilayer film shows a self-propagating exothermic reaction when a minute external shock is applied. Using the reactive film as a heat source for soldering enables us to complete the bonding process instantaneously within a second because of its fast reaction propagation. However, cracks are introduced in the reacted NiAl layer after bonding, which becomes a big problem in the viewpoint of thermal and mechanical reliability. In this study, a laser-induced multiple points ignition technique is developed, and reaction propagation characteristics and crack introducing phenomenon are investigated toward crack propagation control.

Abstract
In this work, sensitivity and response times of PDMS-based capacitive force sensors are enhanced via the modifications of the PDMS layer. Two modifying approaches are proposed; (i) change PDMS’s (elastomer:curing agent) ratio and (ii) adding conductive polymer PEDOT:PSS into the PDMS layer. The change of PDMS (elastomer:curing agent) ratio from (10:1) to (30:1) increases the sensitivity from 0.4 ± 0.08 to 0.72 ± 0.23 kPa−1 (+80%) but it does not significantly affect the response/recovery times. In addition, by adding 1% wt. of PEDOT:PSS to PDMS (30:1), the further increment of sensitivity from 0.72 ± 0.23 to 1.44 ± 0.17 kPa−1 (+100%) and the shorter response time from 1.59 ± 0.02 to 0.45 ± 0.03 s (−72%) are observed. The mechanical and electrical studies reveal that the change of PDMS (elastomer:curing agent) ratio and the adding of PEDOT:PSS to PDMS layer result in the modification of PDMS’s deformability and the increase of charge transportation, leading to the enhancement of sensing characteristics of the sensors.

Published: March 2021

Abstract
Ionic liquids (ILs) have been intensively studied as one promising candidate for an electrolyte in lithium ion batteries (LIBs). Structural analysis of interfaces between an IL-based electrolyte and a LIB electrode would provide beneficial information for improving LIBs. In this study, we investigated the interfacial structures between an IL, 1-ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl)imide (EMI-TFSI), and a spinel-type lithium titanate (Li4Ti5O12) electrode in the presence and absence of Li-salt by frequency modulation atomic force microscopy (FM-AFM) utilizing a quartz tuning fork sensor. Solvation structures on the interface were successfully visualized by two-dimensional frequency shift mapping. Electrochemical impedance spectroscopy measurement was also performed to measure the rate of Li+-ion insertion/extraction on the interface and we found that the interfacial ion-transfer may prevent the formation of layered solvation structure.

Abstract
We present a conceptual design to generate and deliver nanoparticles in one unique system based on electrohydrodynamic atomisation (EHDA) without the restriction of the collector. The present EHDA bipolar configuration consists of a capillary nozzle and a pin, both act as emitters and as the reference electrodes of each other. Under an applied voltage, the capillary nozzle sprays droplets while the pin generates ion wind via corona discharge. During spraying process, droplets’ charge is significantly reduced by interacting with counter ions and propelled away from the electrodes by the momentum of ion winds accumulated from corona discharge. Thus, the present technique can yield promising applications in effective respiratory delivery of nanomedicine.

The Stellar Content of H72.97-69.39, a Potential Super Star Cluster in the Making
Authors: Andersen Morten , Zinnecker Hans , Hirschauer Alec S. , Nayak Omnarayani , Meixner Margaret 
Published: March 2021

Abstract
Young massive clusters and super star clusters (SSCs) represent an extreme mode of star formation. Far-infrared imaging of the Magellanic Clouds has identified one potential embedded SSC, HSO BMHERICC J72.971176-69.391112 (H72.97-69.39 in short), in the southwest outskirts of the Large Magellanic Cloud. We present Gemini Flamingos 2 and GSAOI near-infrared imaging of a 3′ × 3′ region around H72.97-69.39 in order to characterize the stellar content of the cluster. The stellar content is probed down to 1.5 M
⊙. We find substantial dust extinction across the cluster region, extending up to A

K
of 3. Deeply embedded stars are associated with ALMA-detected molecular gas suggesting that star formation is ongoing. The high spatial resolution of the GSAOI data allows identification of the central massive object associated with the 13CO ALMA observations and detection of fainter low-mass stars around the H30α ALMA source. The morphology of the molecular gas and the nebulosity from adjacent star formation suggest they have interacted covering a region of several parsecs. The total stellar content in the cluster is estimated from the intermediate- and high-mass stellar content to be at least 10,000 M
⊙, less than R136 with up to 100,000 M
⊙ within 4.7 pc radius, but places it in the regime of an SSC. Based on the extinction determination of individual stars we estimate a molecular gas mass in the vicinity of H72.97-69.39 of 6600 M
⊙, suggesting more star formation can be expected.
Deciphering the Deep Origin of Active Regions via Analysis of Magnetograms

Published: March 2021

Abstract
In this work, we derive magnetic toroids from surface magnetograms by employing a novel optimization method, based on the trust region reflective algorithm. The toroids obtained in this way are combinations of Fourier modes (amplitudes and phases) with low longitudinal wavenumbers. The optimization also estimates the latitudinal width of the toroids. We validate the method using synthetic data, generated as random numbers along a specified toroid. We compute the shapes and latitudinal widths of the toroids via magnetograms, generally requiring several m's to minimize residuals. A threshold field strength is chosen to include all active regions in the magnetograms for toroid derivation, while avoiding non-contributing weaker fields. Higher thresholds yield narrower toroids, with an m = 1 dominant pattern. We determine the spatiotemporal evolution of toroids by optimally weighting the amplitudes and phases of each Fourier mode for a sequence of five Carrington Rotations (CRs) to achieve the best amplitude and phases for the middle CR in the sequence. Taking more than five causes “smearing” or degradation of the toroid structure. While this method applies no matter the depth at which the toroids actually reside inside the Sun, by comparing their global shape and width with analogous patterns derived from magnetohydrodynamic (MHD) tachocline shallow water model simulations, we infer that their origin is at/near the convection zone base. By analyzing the “Halloween” storms as an example, we describe features of toroids that may have caused the series of space weather events in 2003 October–November. Calculations of toroids for several sunspot cycles will enable us to find similarities/differences in toroids for different major space weather events.
AT2020caa: A Type Ia Supernova with a Prior Outburst or a Statistical Fluke?
Authors: Soraisam Monika , Matheson Thomas , Lee Chien-Hsiu 
Published: March 2021

Abstract
We recently discovered an extragalactic transient, AT2020caa, from the Zwicky Transient Facility alert stream using the community broker ANTARES. This transient apparently exhibited two outbursts within one year (between 2020 and 2021). Based on a decade-long historical light curve of the candidate host galaxy, we rule out activity from the galaxy nucleus to explain these outbursts. The measured peak magnitudes (assuming the known spectroscopic redshift of the candidate host galaxy) put AT2020caa in the realm of thermonuclear supernovae (SNe) or luminous core-collapse SNe. A handful of the latter are known to show prior outbursts (POs), thought to be linked to mass loss in massive stars. Using Gemini/GMOS, we obtained a spectrum of the current outburst that shows it to be a Type Ia supernova. We examine the nature of AT2020caa’s PO seen a year earlier and conclude that it is likely a separate SN within the same galaxy.
Dust in Comet 67P/Churyumov–Gerasimenko: Interrelation between in situ Findings by Rosetta and Ground-based Polarimetry
Authors: Zubko Evgenij , Videen Gorden 
Published: March 2021

Abstract
We present a comprehensive model of the ground-based polarization observations from comet 67P/Churyumov–Gerasimenko using two different apertures on its apparitions of 1982 and 2016. Our modeling suggests that the dust composition viewed within the two apertures is the same, but that they have different size distributions, with smaller particles more concentrated in the innermost coma. The best fits to the measurements using the smallest aperture are obtained using a dust size distribution similar to the Rosetta findings. Furthermore, the model parameters providing the best fit to polarimetric observations using the large aperture appear remarkably consistent with what was previously inferred in other comets. This represents an attempt to reconcile the Rosetta results with ground-based observations.

Published: March 2021

The current data paper aims to interlink the African plant collections of the Meise Botanic Garden Herbarium (BR) and the Royal Museum for Central Africa Xylarium (Tw). Complementing both collections strengthens the reference value of each institutional collection, as more complete metadata are made available and it enables increased quality control for the identification of wood specimens. Furthermore, the renewed connection enables the linking of available wood trait data with data on phenology, leaf morphology or even molecular information for many tree species, allowing assessments of performance of individual trees. In addition to studies at the interspecific level, comparisons at the intraspecific level become possible, which could lead to important new insights into resilience to and impact of global change, as well as biodiversity conservation or forest management of Central African forest ecosystems.
By interlinking the Tervuren Xylarium Wood database with the recently digitised herbarium of Meise Botanic Garden, we were able to establish a link between 6,621 xylarium and 9,641 herbarium records for 6,953 plant specimens. Both institutional databases were complemented with reliable specimen metadata. The Tervuren xylarium now profits from taxonomic revisions made by botanists at Meise Botanic Garden and a list of phenotypical features for woody African species can be extended with wood anatomical descriptors. New metadata from the Tw xylarium records were used to add the country of collection to 50 linked BR herbarium specimens for which this information was missing. Furthermore, metadata available from the labels on digitised BR herbarium specimens was used to update Tw xylarium records with the date of collection (817 records), collection locality (698 records), coordinates (482 records) and altitude (817 records). In conclusion, we created a reference database with reliable botanic identities which can be used in a range of studies, such as modelling analyses, community assessments or trait analyses, all framed in a spatiotemporal context. Furthermore, the linked collections hold historical reference data and specimens that can be studied in the context of global changes.

Published: March 2021

Introduction: The goal of our study was to develop a risk-oriented algorithm for the combined use of hemostatics and anticoagulants in patients after total arthroplasty of the knee or hip joints to reduce the risk of thrombohemorrhagic complications.
Materials and methods: We performed a retrospective study (n=253). In group (Gr.) 1, the time interval (TI) between the administration of hemostatic and anticoagulant prophylaxis was ≤17 hours (n=145; 57.31%), and in Gr. 2 – 18-24 hours (n=108; 42.68%). We analyzed the influence of different factors on the development of thrombosis and bleeding cases after the operation.
Results and discussion: Thrombohemorrhagic complications were observed in 27 (10.67%) patients. Thrombosis in Gr. 1 was associated with the use of tranexamic acid, and were recorded 2.2 times more often than in Gr. 2 (p<0.05). The development of thrombosis in Gr. 1 was influenced by: class II obesity, type 2 diabetes mellitus, myocardial infarction, venous pathology, age of patients >75 years, for women – an initially low level of international normalized ratio, and activated partial thromboplastin time (APTT) (p<0.05). The development of bleeding in Gr. 1 was influenced by: age >75 years, among men and women – an increased preoperative level of APTT, for women – a decreased level of fibrinogen and platelets (p<0.05).
Conclusion: To prevent thrombosis and bleeding after arthroplasty of large joints, the TI between the use of hemostatics and anticoagulants should be at least 18 hours, especially in patients with the above risk factors, in particular, when using tranexamic acid and low molecular weight heparins.
