E3SN: Efficient End-to-End Siamese Network for Video Object Segmentation
Authors: Lan Meng , Zhang Yipeng , Xu Qinning , Zhang Lefei
Published: July 2020

In the semi-supervised video object segmentation (VOS) field, SiamMask has achieved competitive accuracy and the fastest running speed. However, the two-stage training procedure requires additional manual intervention, and using only single-level features does not maximize the rich hierarchical feature information. This paper proposes an efficient end-to-end Siamese network for VOS. In particular, a supervised sampling strategy is designed to optimize the training procedure. Such an optimization facilitates the training of the entire model in an end-to-end manner. Moreover, a multilevel feature aggregation module is developed to enhance feature representability and improve segmentation accuracy. Experimental results on DAVIS2016 and DAVIS2017 datasets show that the proposed approach outperforms the SiamMask in accuracy with similar FPS. Moreover, this approach also achieves good accuracy-speed trade-off compared with that of other state-of-the-art VOS algorithms.

This research aims to describe the teacher's explanation in constructing the meaning of learning containing the living environment in Indonesia. This research uses descriptive explanatory method. The research was conducted by observing and analyzing classroom learning discourse in elementary schools labeled Adiwiyata or school whose learning is related to the living environment education. The results of the study show that the teacher's explanation contains an explanation of the object, concepts, and procedures; the explanatory strategy used by the teacher is a knowledge-transforming with a reference to the social and cultural context of the society that consists of (1) religiosity (2) dependence between humans and the environment, (3) human values to preserve nature, (4) social and cultural ethics as basic human characteristics. Verbal or linguistic strategies show the teacher's awareness in using language with metaphors and expressions to motivate. Through a verbal strategy it is known that the teacher's explanation is done efferently and aesthetically. The teacher's explanation constructs the meaning of descriptive and procedural knowledge. Descriptive knowledge is knowledge that makes the learner knows or understands. Procedural knowledge makes the learner is able to. The role of teacher explanation is supported by the government's active role in environmental sustainability programs.

Published: July 2020

A novel coronavirus (SARS-CoV-2) has caused a major outbreak in human all over the world. There are several proteins interplay during the entry and replication of this virus in human. Here, we have used text mining and named entity recognition method to identify co-occurrence of the important COVID 19 genes/proteins in the interaction network based on the frequency of the interaction. Network analysis revealed a set of genes/proteins, highly dense genes/protein clusters and sub-networks of Angiotensin-converting enzyme 2 (ACE2), Helicase, spike (S) protein (trimeric), membrane (M) protein, envelop (E) protein, and the nucleocapsid (N) protein. The isolated proteins are screened against procyanidin-a flavonoid from plants using molecular docking. Further, molecular dynamics simulation of critical proteins such as ACE2, Mpro and spike proteins are performed to elucidate the inhibition mechanism. The strong network of hydrogen bonds and hydrophobic interactions along with van der Waals interactions inhibit receptors, which are essential to the entry and replication of the SARS-CoV-2. The binding energy which largely arises from van der Waals interactions is calculated (ACE2=-50.21 ± 6.3, Mpro=-89.50 ± 6.32 and spike=-23.06 ± 4.39) through molecular mechanics Poisson-Boltzmann surface area also confirm the affinity of procyanidin towards the critical receptors.
Exchange Spin Coupling from Gaussian Process Regression
Authors: Bahlke Marc Philipp , Mogos Natnael , Proppe Jonny , Herrmann Carmen
Published: July 2020

Heisenberg exchange spin coupling between metal centers is essential for describing and understanding the electronic structure of many molecular catalysts, metalloenzymes, and molecular magnets for potential application in information technology. We explore the machine-learnability of exchange spin coupling, which has not been studied yet. We employ Gaussian process regression since it can potentially deal with small training sets (as likely associated with the rather complex molecular structures required for exploring spin coupling) and since it provides uncertainty estimates (“error bars”) along with predicted values. We compare a range of descriptors and kernels for 257 small dicopper complexes and find that a simple descriptor based on chemical intuition, consisting only of copper-bridge angles and copper-copper distances, clearly outperforms several more sophisticated descriptors when it comes to extrapolating towards larger experimentally relevant complexes. Exchange spin coupling is similarly easy to learn as the polarizability, while learning dipole moments is much harder. The strength of the sophisticated descriptors lies in their ability to linearize structure-property relationships, to the point that a simple linear ridge regression performs just as well as the kernel-based machine-learning model for our small dicopper data set. The superior extrapolation performance of the simple descriptor is unique to exchange spin coupling, reinforcing the crucial role of choosing a suitable descriptor, and highlighting the interesting question of the role of chemical intuition vs. systematic or automated selection of features for machine learning in chemistry and material science.

Published: July 2020

In this work, we generate a battery performance and thermal dataset specific to eVTOL use-cases and develop a fast and accurate performance and degradation model around that dataset. We use a machine-learning based physics-informed battery performance model to break the typically observed accuracy-computing cost trade-off. We fit the aging parameters for each cycle in a given cell's lifetime, and then model the evolution of those parameters using a new approach that combines traditional physics-based models, consisting of SEI film growth, charge loss, and Li Plating, along with a neural network in a universal ordinary differential equations (u-ODEs) framework.
Layer-by-Layer Structural Identification of 2D Ruddlesden-Popper Hybrid Lead Iodide Perovskites by Solid-State NMR Spectroscopy
Authors: Lee Jeongjae , Lee Woocheol , Kang Keehoon , Lee Takhee , Lee Sung Keun
Published: July 2020

Application of two-dimensional (2D) organic-inorganic hybrid halide perovskites for optoelectronic devices requires detailed understanding of the local structural features including the Pb-I bonding in the 2D layers and the capping ligand-perovskite interaction. In this study, we show that 1H and 207Pb solid-state Nuclear Magnetic Resonance (NMR) spectroscopy can serve as a non-invasive and complementary technique to quantify the composition and to probe the local structural features of 2D Ruddlesden-Popper phase BA2MAn-1PbnI3n+1 (n=1-4) with butylammonium (BA) spacers. 207Pb echo and 1H-detected 207Pb→1H heteronuclear correlation (HETCOR) experiments enables layer-by-layer structural detection of 2D halide perovskites. We show that the observed correlation between 207Pb NMR shifts and mean Pb-I bond lengths around each Pb site allows us to probe the local bonding environment of Pb via its 207Pb NMR shift. We envisage that this technique will be vital for better understanding the materials properties as determined by the local atomistic environments in multi-dimensional halide perovskites.

Framework materials at the molecular level, such as metal-organic frameworks (MOF), were recently found to exhibit exotic and counterintuitive micromechanical properties. Stimulated by host-guest interactions, these so-called soft porous crystals can display counterintuitive adsorption phenomena such as negative gas adsorption (NGA). NGA materials are bistable frameworks where the occurrence of a metastable overloaded state leads to pressure amplification upon a sudden framework contraction. How can we control activation barriers and energetics via functionalization of the molecular building blocks that dictate the frameworks’ 30 mechanical response? In this work we tune the elastic and inelastic properties of building blocks at the 31 molecular level and analyze the mechanical response of the resulting frameworks. From a set of 11 frameworks, we demonstrate that widening of the backbone increases elasticity, while elongation of the building blocks results in a decrease in critical yield stress of buckling. We further functionalize the backbone by incorporation of sp3 hybridized carbon atoms to soften the molecular building blocks, or stiffen them with sp2 and sp carbons. Computational modeling shows how these modifications of the building blocks tune the 36 activation barriers within the energy landscape of the guest-free bistable frameworks. Only frameworks with free energy barriers in the range of 800 to 1100 kJ mol–1 37 per unit cell, and moderate yield stress of 0.6 to 38 1.2 nN for single ligand buckling, exhibit adsorption-induced contraction and negative gas adsorption. Advanced experimental in situ methodologies give detailed insights into the structural transitions and the adsorption behavior. The new framework DUT-160 shows the highest magnitude of NGA ever observed for nitrogen adsorption at 77 K. Our computational and experimental analysis of the energetics and mechanical response functions of porous frameworks is an important step towards tuning activation barriers in dynamic framework materials and provides critical design principles for molecular building blocks leading to pressure amplifying materials

Base metal-catalyzed oxidative conversion of ammonia into dinitrogen is a promising process to utilize ammonia as an energy carrier. In this study, we report the manganese-catalyzed ammonia oxidation under chemical and electrochemical conditions. Mechanistic studies including density functional theory (DFT) calculations suggest that a nucleophilic attack of ammonia on manganese nitrogenous complexes occurs to form a nitrogen–nitrogen bond leading to dinitrogen.
High Pressure High Temperature Synthesis of Highly Boron Doped Diamond Microparticles and Porous Electrodes for Electrochemical Applications
Authors: Wood Georgia , Newton Mark , Shkirskiy Viacheslav , Unwin Patrick R. , Macpherson Julie , Munday Mark , Walters Carmen
Published: July 2020

High pressure high temperature (HPHT) synthesis of crystallographically well-defined boron doped diamond (BDD) microparticles, suitable for electrochemical applications and using the lowest P and T (5.5 GPa and 1200°C) growth conditions to date, is reported. This is aided through the use of a metal (Fe-Ni) carbide forming catalyst and an aluminum dibromide (AlB2) boron source. The latter also acts as a nitrogen sequester, to reduce boron-nitrogen charge compensation effects. Raman microscopy and electrochemical measurements on individual microparticles reveal they are suitably doped to be considered metallic-like and contain negligible sp2 bonded carbon. A compaction process is used to create macroscopic porous electrodes from the BDD microparticles. Voltammetric analysis of the one-electron reduction of Ru(NH3)63+ reveals large capacitive and resistive components to the current-voltage curves, originating from solution trapped within the porous material. Scanning electrochemical cell microscopy (SECCM) is employed to map the local electrochemical activity and porosity at the micron scale. These electrodes retain the advantageous properties of polycrystalline BDD grown by chemical vapor deposition, such as large aqueous solvent window and resistance to corrosion, but with the additional benefits of a high, electrochemically accessible, surface area.
Switchable Supracolloidal 3D DNA Origami Nanotubes Mediated through Fuel/Antifuel Reactions
Authors: Walther Andreas , Groeer Saskia
Published: July 2020

3D DNA origami provide access to the de novo design of monodisperse and functional bio(organic) nanoparticles, and complement structural protein engineering and inorganic and organic nanoparticle synthesis approaches for the design of self-assembling colloidal systems. We show small 3D DNA origami nanoparticles, which polymerize and depolymerize reversibly to nanotubes of micrometer lengths by applying fuel/antifuel switches. 3D DNA nanocylinders are engineered as basic building block with different numbers of overhang strands at the open sides to allow for their assembly via fuel strands that bridge both overhangs, resulting in the supracolloidal polymerization. The influence of the multivalent interaction patterns and the length of the bridging fuel strand on efficient polymerization and nanotube length distribution is investigated. The polymerized multivalent nanotubes disassemble through toehold-mediated rehybridization by adding equimolar amounts of antifuel strands. Finally, Förster Resonance Energy Transfer yields in situ insights into the kinetics and reversibility of the nanotube polymerization and depolymerization.

Kapan Allah Membuat Segalanya Indah: Misteri Waktu dalam Kitab Pengkhotbah 3:11
Authors: Nursantosa Andre Putranto
Published: July 2020

“God makes each thing beautiful in its time.” This quote has somewhat found its common usage in social media. People have some habit of quoting this expression whenever they encounter difficulties so as to comfort themselves. Through these words, a person might hope earnestly that “God will help me or provide me with the ‘beautiful’ time someday.” But the question that immediately follows is “When?” What if the burden stays and life remains unchanged? Not many of the fans of these wise words know that the saying originates from the Book of Ecclesiastes (3:11), which in itself is a form of ancient Hebrew literature. In the complete verse of the Book, the clause “He hath made every thing beautiful in his time is followed by another clause, “also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.” The later part of the verse (3:11b) is often ignored. However, by accepting the words that “God hath set the world in their heart”, one realises that he or she cannot fathom God’s mind, but might make peace and accept that divine question. Hence, one might realise that both good times and the not-so-good times could be but “beautiful times” for oneself.

Kontribusi Fenomenologi Post-Subjek pada Metodologi Filosofis dan Teologis
Authors: Tedjoworo Hadrianus
Published: July 2020

Givenness is probably an odd term in methodology, but not in phenomenology. The long history of subjectivism in philosophy faces confrontations from Derrida's deconstruction. This history also results in a sort of mutual exclusion between philosophy and theology. The concept of the subject becomes a problem for both, but frequently it is safeguarded for the sake of a more universal 'objectivity'. The phenomenological tendency towards phenomenon, more than towards the experiencing subject and more than anything regarded as object, provokes some philosophical focus on the emancipation of the phenomena. Marion pushes phenomenology to its limits, to the extent that he is suspected of undermining the role of the subject in contemporary philosophical discourse. He reacts to Derrida's deconstruction, which was also criticised for not offering a way out of the labyrinth from the collapse of traditional thoughts. Marion is quite consistent with his phenomenology, namely in offering a way out for the subject to be a witness, and reminds that philosophy should be more appreciative of phenomena. The term saturated phenomenon represents his philosophical thinking that can be regarded as a methodological approach to respect, and not to dominate, reality. Being a witness is not the same as playing a critic on reality. This could be a useful stance for philosophers as well as theologians in the presence of the phenomena they cannot master, namely, the given phenomena.
Contextual Philosophy-Learning at the Faculty of Theology, Sanata Dharma University
Authors: Mulyatno Carolus Borromeus
Published: July 2020

Philosophy learning is an integral part of the educational formation at the Faculty of Theology, Sanata Dharma University, Yogyakarta, Indonesia. It is integrated with theology and other sciences learning to shape the identity of the faculty and to contribute to the development of the community. The focus of this writing is to answer two questions: What are the basic considerations for choosing philosophy learning in this faculty? How can method choice be accounted for? By attending to the faculty’s history, the author finds that the basic considerations for choosing philosophy learning method at the faculty are the history faculty establishment and its academic vision. Historically, the existence of the faculty was related to the efforts of Semarang Archdiocese for priest preparation and local pastoral activist education. Philosophy learning is also related to the faculty’s academic vision that leads the students towards concrete involvement in building the church living in the context of pluralism in Indonesia. Inspired by Heidegger’s idea on phenomenological method, preferences to select existential analysis method for philosophy learning in the faculty contribute to the development of contextual theological reflection as well as to priest and pastoral worker preparation, by involving students in community life, dialogue, and living together in the society, based on the values from the local wisdom that are still relevant today.

Iot architecture that supports the stimulation of gross motor development in children aged 5-6 years using drop box game
Authors: Wajdi Halim , Suwastika Novian Anggis , Yasirandi Rahmat
Published: July 2020

Gross motor development in children influences the development of self-confidence and the concept of self-formation as they mature. Many people assume that gross motor development is often ruled out compared to other aspects of child development because the perception of gross motor development will automatically increase with age, when in fact the gross motor development must continue to be stimulated so that it develops perfectly. The activity used in this research is the game of putting balls into a hole by moving the game box (Drop Box). This research aims to build a device that has been designed and assess the ability/performance of the system based on the parameters of functionality, the accuracy of values , and reading speed. In this research, the Drop Box game implements Internet of Things (IoT) to support recording activities and processing data obtained from recording children's activities. In this research also proposed a suitable IoT architecture and has been applied in the development of the Drop Box game device. We carry out functional system testing and system performance testing based on accuracy parameters and speed-reading parameters. The test results show that the functionality of the system runs with an average of 100%.

O objetivo desse estudo foi caracterizar a ocorrência de predação a rebanhos domésticos em pequenas propriedades rurais do entorno de áreas protegidas da Mata Atlântica do Estado de Pernambuco, Brasil. Ao todo, foram visitadas 11 pequenas propriedades próximas à Estação Ecológica de Tapacurá (n=6), em São Lourenço da Mata, e à área protegida da 10ª Brigada de Infantaria Motorizada (n=5), em Recife. Nas propriedades, foram aplicados questionários aos proprietários, no intuito de obter dados sobre os ataques ocorridos aos animais domésticos por animais silvestres, assim como, obter informações sobre as características ambientais da propriedade, espécies criadas, tamanho do rebanho, sistemas de criação e manejo adotado. Em 54,5% (6/11) das propriedades foram relatados casos de predação. As galinhas foram predadas em 60% (9/15) dos casos e os cachorros-do-mato (Cerdocyon thous) foram os principais predadores de animais domésticos, responsáveis por 40% (4/15) dos ataques. Foi observada correlação negativa entre a ocorrência de predação e a presença de cercas-vivas na propriedade, e positiva entre ocorrência de predação e distância da propriedade em relação à área protegida e fontes naturais de água na propriedade.

Os malófagos são piolhos mastigadores, encontrados em aves e mamíferos. Nas emas (Rhea americana) podem causar grandes prejuízos ao comércio, devido à perda da qualidade das plumas, danificação das penas, lesões na pele e debilidade. Sendo assim, objetiva-se com o estudo relatar a infestação por piolhos em emas criadas em cativeiro. Os piolhos foram preservados em álcool 70%, clarificados com lactofenol e montadas as lâminas para observação em microscópio óptico. Nas emas observou-se alterações como desidratação, pele descamada e áspera, penas deformadas, falhadas e opacas e presença de piolhos malófagos da espécie Struthiolipeurus rheae.

Published: July 2020

A parvovirose canina é causada pelo parvovírus canino tipo 2 (CPV-2) e consiste em uma enfermidade mundialmente conhecida na medicina de cães, uma vez que é altamente contagiosa, caracterizada principalmente por episódios de hematoquezia, vômitos e desidratação. No Brasil, milhares de animais são infectados todo ano, sendo a via oronasal a principal forma de contágio. A mortalidade é relativamente grande já que a doença possui apenas tratamento sintomático e os animais chegam ao ambulatório em estágio crítico. Sabe-se que a vacinação reduz drasticamente a incidência da doença, porém, a evolução do vírus ainda levanta questões sobre a eficácia de algumas vacinas já que alguns animais, mesmo vacinados, acabam desenvolvendo a virose. A presente revisão aborda aspectos relacionados à parvovirose canina como: seu histórico, grupos de risco, fontes de infecção, sinais clínicos, dados epidemiológicos, métodos de diagnóstico, vacinação e tratamento.

Published: July 2020

The role of classification in science and other spheres can hardly be underestimated. Accounting is no exception. The requirements to “natural classification” were formulated in the late twentieth century and can be used for further development and improvement of accounting. The article is devoted to the analysis of the accounting system for compliance with the requirements of natural classification. Accounting information is generated on the basis of classification, with accounts themselves used as classification criteria. The existing system of accounting was analyzed for compliance with the major twelve natural classification requirements to find out that the system is totally incompliant with five of these requirements and five more are met only partially. In order to analyze the accounting system for compliance with the remaining two requirements it is necessary to start with decomposition of accounts into separate classification groups. The methods of scientific classification, formal logic, comparison, analysis and synthesis are used in this work. The results of the study can be used to improve the organization and planning of scientific research in the field of accounting. The research is of practical significance as it provides the recommendations on changing the composition and special features of accounts to meet the requirements of natural classification which in turn will reveal the very essence of the subject area in multidimensional and logical way.
