Authors: Do Linh Hoai , Bui Trang Thu , Nguyá»…n Huy Quang , Le Anh Viet , Do Phuong Thu , Nguyen Anh Tram
Published: May 2020

The research aims to analyze determinants of the division of household labor in Vietnam. Research model and hypotheses are developed based on the Theory of Planned Behavior - TPB (Icek Ajzen, 1985) with primary data from questionnaires survey. With 295 respondents during the period from November 2019 to April 2020, the study utilizes SPSS 20.0 software to test research model and hypotheses. The results show that â€œThe Intention of Household Labor Divisionâ€ is significantly affected by â€œAttitudeâ€, along with â€œSubjective Normsâ€ (Gender Viewpoint) and â€œPerceived Behavioral Controlâ€; the weakest determinants influencing â€œThe Intention of Household Labor Divisionâ€ comprise â€œSubjective Normsâ€ (Friend), â€œSubjective Normsâ€ (Family) and â€œSubjective Normsâ€ (Social Environment). By contrast, â€œThe Intention of Household Labor Divisionâ€ influences â€œThe Behavior of Household Labor Divisionâ€ to the highest extent, followed by â€œPerceived Behavioral Controlâ€. Based on these findings, some recommendations are proposed to enhance the efficiency of the division of household labor, including (1) active involvement of government; (2) adjusting awareness; and (3) the right attitude.

Human activities in utilizing natural resources, including in coal activities without conservation measures will cause environmental damage, among others, the danger of erosion. One of the impacts of erosion is declining land productivity, so it is necessary to follow up in the form of rehabilitation of forests and land. This research aims to identify the estimation of erosion rate on the post-mining land of PT Berau Coal planted with citronella grass and the financial feasibility of citronella grass revegetation. The field method is conducted through surveys and observations to determine the length of slope and slope of a slope. Determination of the sampling point in this study using stratified sampling technique.  Sampling point is all revegetation land planting citronella grassand cover crop there are 6 sampling points. The observed parameters include soil properties, erosion predictions occurring, erosivity factors, soil erosiveness, slope length and slope, crop factor and land conservation, tolerable erosion, and danger level erosion. The results showed the magnitude of the value of the alleged erosion rate by using the USLE method at the research site planted by the seraiwangi plants has considerable erosion potential ranging from a 12% slope of 891.98 tons/ha/yr while the highest soil erosion at the Pit H4 SW L study site at a 30% slope of 3060.10 tons/ha/yr.
The back side of the postcard: Subversion of the island tourist gaze in the contemporary Mallorcan imaginary
Authors: Picornell Mercè
Published: May 2020

This article analyses the manner in which certain artists and activists in Mallorca have recently generated a counter-image of the traditional postcard, which essentially symbolises the tourist gaze. Taking examples from diverse sources, such as artistic pieces, memes, protest posters and underground comics, I analyse the mechanisms used to subvert the conventional tourist perspective of the island space. More specifically, I identify two strategies associated with the limitation of the space and time portrayed in the postcard. The confines of the space are manifest in the display of the off-camera and the critical anchorage of the image, while the limits of temporality are presented in a dystopic revision of the island map. To support the findings of this study, I have drawn on the ideas, theories and methods of island studies, tourism studies, postcolonial criticism and the rhetoric of images. The conclusions of this article aim to provide an interpretation of the complex emergence of a resistant social agency capable of creating its own portrayals of the island.
De máquinas sociales y engranajes humanos. La cárcel, lo abyecto y lo perverso en «El sexto» de José María Arguedas
Authors: Leonardo-Loayza Richard
Published: May 2020

Este artículo estudia El sexto (1961) de José María Arguedas. Nuestro objetivo es demostrar que el autor de esta obra pretende evidenciar, que el capitalismo emplea la cárcel y los reclusos encerrados en este lugar para someter, controlar y castigar a aquellos que se atreven a oponerse a su influencia en el Perú. En este sentido, no se trata solo de una novela carcelaria, en la que se evoca una experiencia particular desgarradora, sino de un texto político en el que se pone de manifiesto algunas de las estrategias, instrumentos y mecanismos que se utilizan para doblegar la voluntad de los individuos insurrectos a dicho sistema.

Política de Estado en edición de libros en la norpatagonia: el Fondo Editorial Neuquino (FEN)
Authors: Bertuzzi Mauricio C.
Published: May 2020

En el año 1989, la provincia de Neuquén crea el Fondo Editorial Neuquino (FEN) por Ley Nº 1.809 con el objetivo de publicar, difundir y vender obras de los escritores provinciales. Su puesta en funcionamiento y evolución fue dispar; a lo largo de los años tuvo diversas propuestas de modificación. La última de ellas, impulsada desde la Subsecretaría de Cultura (ahora con rango de Ministerio) concluyó a fines de 2018 en la redacción y aprobación de la Ley Nº 3.164, que la reemplaza.

Este proyecto editorial se solapó en sus 30 años de existencia con otros aportes de entidades estatales para publicar libros neuquinos, y coincidió en sus inicios con otras legislaciones provinciales similares en la Norpatagonia: en Río Negro surgió el Fondo Editorial Rionegrino en 1984, y un año después en La Pampa se reglamentó el Fondo Editorial Pampeano.

El presente trabajo describe y analiza el FEN poniendo de relieve particularidades de su redacción y puesta en funcionamiento. Busca discutir debilidades en su implementación, para contribuir al fortalecimiento de las estrategias públicas de edición de libros, considerando que la función del Estado para articular políticas activas es importante para promover e incrementar la bibliodiversidad del ecosistema libro argentino.

O acesso à informação através da internet ganha a cada dia mais espaço em nossa sociedade, inclusive entre crianças e adolescentes. O estudo teve como objetivo identificar tendências de pesquisas sobre o uso seguro da informação on line por crianças e adolescentes relacionadas à competência informacional. Foi realizado um levantamento na base de dados SCOPUS e após refinamento dos resultados obteve-se 71 referências. Como os resultados observou-se que os Estados Unidos e o Reino Unido são os países que mais publicam sobre a temática e que 52.9 % das produções se tratam de artigos científicos. Verificou-se que os documentos analisados ressaltam a importância de que orientações sobre o tema ocorram na escola, com destaque para o papel da biblioteca escolar, visto que na escola pública este é o local em que os estudantes mais acessam a internet. Verificou-se também que o tema uso seguro da informação abrange muitos outros subtemas: exposição de dados, abuso sexual, cyberbullying. Concluiu-se que a pesquisa sobre uso seguro da informação em ambientes online é complexa e que a área carece de pesquisas sobre a temática, em particular no Brasil, visando obter mais subsídios que permitam conhecer melhor esta questão e tendo a escola como espaço de aplicação, discussão e orientação que possibilite o desenvolvimento de habilidades para uma navegação mais segura por adolescentes.

Published: May 2020

The development of technology and design methods in architecture continues, for example, parametric design methods and the application of digital fabrication technology to create models of representation and construction. Digital fabrication defined the process of manipulating objects using a CNC router, 3d printer, and laser cutter using a reduction or addition method. Studying digital fabrication technology is now a demand for academics and professionals in the field of architecture. Both architecture instructors and students are now required to increase their understanding and ability to process digital designs into scale-scale representation through a digital fabrication process.Through this research, researchers will describe the learning process of digital laser cut fabrication applications using parametric design methods, which are in the form of developing a Voronoi diagram-based design. Parametric design development will be carried out using Rhino software with Grasshopper. This research activity was carried out in the Department of Architecture FST Campus 2, University Technology of Yogyakarta. This research divided into several activities, namely the digital design process, the fabrication preparation process, and the installation or assembly of the model. Also, researchers will explain the obstacles or problems faced in each activity, as well as the opportunities and challenges of digital fabrication applications in architecture.The results of the study showed a clear process in each phase of the activity, and the explanation complemented by obstacles or problems encountered and problem-solving. Failures that occur in the fabrication process provide learning that digital design and digital fabrication are a unified, interconnected process. The opportunities and challenges of digital fabrication applications in the architectural world are further interesting considerations to discuss.

Published: May 2020

Gasification is a process of converting carbon-containing compounds to convert both liquid and solid materials into fuel-capable gas (CO, H2, CO2, CH4, and H2O) through the combustion process with limited air supply. Gasification that we have known so far is gasification with coal feed and agricultural waste, but gasification with livestock waste feed has never been done. In this study the gasification feed material used horse dung biomass with a gas agent in the form of oxygen. The purpose of this study was to determine the effect of oxygen flow rate (4 variations namely 10, 15, 20 and 30 lt / min) in the process of gasification of horse dung (produced 4 fuels namely syngas A, syngas B, syngas C and syngas D) on the performance capabilities of a 100 cc engine. The stages of the research carried out were drying feed material, gasification process, syngas storage and testing on a 100 cc engine with various variations of rotation (4 variations namely 1500, 2500, 3500 and 4500 rpm). The results obtained from this study are the highest torque and effective power obtained in syngas A fuel for various engine speeds. At 4500 rpm, a torque of 6.7 Nm is obtained, while an effective power of 3156 Watts is used to test engine results using Syngas A fuel.

Technology of Building Locally Detailed Differential Grids for the Calculation of Affected Areas at Gas and Dust Explosions in Coal Mines
Authors: Lukashov O. Yu. , Kostromin D. A.
Published: May 2020

The article describes the technology of discretization of the computational domain for solving unsteady gas-dynamic problems in the field of industrial safety of coal mines. The most important of this problem is the calculation of the parameters of air shock waves and the affected areas during methane explosions in mine workings. The technology allows you to automate the construction of a differential grid for a spatial network of mine workings, taking into account the features of the mines topology and simulated processes. At the same time, the grid can consist of cells of various dimensions – one-dimensional, two-dimensional and three-dimensional. The aim of the work is to create the basics for the development of scientific research of gas-dynamic processes in gas explosions in mining workings by taking into account new factors – means of explosion protection, the participation of coal dust, etc. The tasks of the work include: developing an addressing system for identification and quick access to arbitrary cells of the difference grid; the construction of unambiguous spatial relationships between the corresponding faces of the cells during their splitting and combining; testing of the technology on the mine network of a real mine. A new approach in the work is the possibility of automating the partition of the computational domain with the simultaneous use of cells of all three dimensions. The article contains details of the implementation of technology. The article shows the results of splitting the network of mine workings in a real coal mine, the results of calculations using the obtained grid and the convergence of the results to a solution when reducing the step as a result of subsampling the computational domain with different depth of splitting.
Entomological Images in the Worldview of the Buryats
Authors: Badmaev Andrew A.
Published: May 2020

Purpose. The aim of this study is to identify a set of traditional views of the Buryats associated with insects. Results. In the popular zoological classification of the Buryats, the insects were distinguished as a separate class due to their small size. Another sign of this class was the characteristic of insects being nimble. Insects were divided into such groups as “winged insects”, “worms and beetles”, “social insects” and others. Images of insects that live in the sky, water and on earth were not always determined by their habitat. According to the Buryat views, there was a group of chthonic creatures, such as midges, flies, lice, fleas and beetles. At the same time, there existed a popular belief that insects appeared as falling from the sky. By contrast with other classes of animals, insects in Buryats beliefs were not personified in a single spirit as the patron of insects. Images of representatives of the order of Lepidoptera, such as butterflies and moths, are rarely present in the traditional worldview of the Buryats. According to their views, in addition to the presence of wings, the most important feature of many Diptera insects is their ability to produce monotonous sounds while flying – buzz, and this quality is reflected in the Buryat vocabulary. The Buryats believed that certain insects had unique features. For instance, the bee had a feminine essence. It is worth noting that the bee was included into a limited group of animals, together with a swallow and an ant, whose presence in the Buryat dwelling was considered favorable for the life of the family. According to the Buryats’ mythological views, only ants had a hierarchy in their groups.
Conclusion. Our analysis has shown that insects were not very important creatures in the Buryats’ beliefs. However, some insects had distinct characteristics. The ant and the bee were considered to be positive, while the gadfly, mosquito, wasp, moth, bug, louse and flea negative. It should also be noted that the chthonic origin of the ant did not determine its final connotation. The Buryats often compared insects to other animal species. The material considered shows that they associated a soul with opposite images of bees and wasps. Some insects were connected with the idea of lycanthropy and the symbolism of fertility, such as the ant and the bee. Unlike other classes of animals, insects were vaguely represented in the myth-ritual practices of the Buryats. Some Buryat views on insects find parallels with the mythological judgments of other peoples, such as the Mongols, Slavic tribes, etc., which is explained by the universal character of the images, typological coincidences and intercultural contacts (primarily with the Mongols).
Names for Houses and Some Issues on Their Genesis in the Traditional Khakass Culture
Authors: Prishchepa Evgeniy V.
Published: May 2020

Purpose. The article is devoted to the study of nominating the items of traditional Khakass housing in the Sayan-Altai region. We considered difficult issues of their genesis focusing on a number of poorly researched types of housings.
Results. The study analyzes the use of the names of traditional Khakass dwellings that are well-known in Ethnography, including their rare dialect nominations recorded by domestic ethnographers. It is noted that some nominations studied are used to determine a house as an object of material culture, whereas other nominations demonstrate a clarifying characteristic, which ultimately determines the differences in the nominations. We considered interpretations of the names of a number of nomad dwellings, such as the name of an archaic housing of taiga Khakass “at ib”. Genesis of the dwellings names is shown in relation to log housings (tura) and frame-pillar constructions (at ib, otah / otag) of the Khakass, which represents a modern trend of studying the Khakass’ material culture.
Conclusion. It is necessary to classify the names of Khakass dwellings known by describing their types. A number of issues relating to the genesis and origin of the types of dwellings studied in relation to otah / otag is still open and requires more additional data. In our opinion, the problem of the genesis of the Khakass dwelling tura, which features a log wooden construction, has been solved and shows its autochthonous character.

Authors: Derevyanko Evgeniya I. , Molodin Vyacheslav I. , Nenakhova Yuliya N.
Published: May 2020

Purpose. The 75th anniversary of the Victory in the Great Patriotic War is celebrated in Russia in 2020. This article focuses on the research activities of Academician A. P. Okladnikov, whose mission during the Great Patriotic War of 1941–1945 was to study Yakutia’s ancient history.
Results. Yakutia is located in the north-eastern part of Siberia. It is the largest administrative and territorial subject of Russia (3,083,523 square kilometers or 1,190,555 square mile) with a great natural economic and resource potential. The Soviet period in the history of the region is associated with its large-scale development. A. P. Okladnikov’s research initiated the systematic study of Yakutia’s ancient history. His research was conducted during the hardest time for Russia, the Great Patriotic War of 1941–1945. Back in 1939, a well-known young scientist, who had earned a PhD and was the author of several discoveries in Siberia and Central Asia, received an invitation from the Institute of Culture under the Council of People’s Commissars of the Yakut ASSR to do archaeological research in the Lena River valley. During the following six years his life was devoted to ancient Yakutia. Conclusion. The monumental task of writing the history of this region was fully implemented. The studies of A. P. Okladnikov are appreciated locally by the State and internationally by the scientific community. The scientist was awarded the medal “For Valiant Labour during the Great Patriotic War of 1941–1945” and two “Badge of Honor” orders. His scientific ideas are so fundamental that are still highly regarded by students, colleagues and modern researchers.
A Methodological Seminar “Preservation of the Objects of Archaeological Heritage of Russian Asia: Results and Trends”
Authors: Bychkov Dmitry A. , Pavlenok Konstantin K. , Vybornov Anton V.
Published: May 2020

Purpose. In modern society, issues of preserving cultural heritage are of constant relevance. This is due to the ongoing struggle for the realization of the interests of a large number of agents. The participants in this process are executive authorities, academic institutions, commercial organizations and economic entities. The interests of each agent are in their own plane whose extreme points intersect with the planes of other agents. Consequently, all parties involved in preserving cultural heritage have points of convergence of their interests. In order to arrange preservation of cultural heritage as a common project, it is necessary to develop communication at the points of convergence of the interests. For this purpose, the Institute of Archaeology and Ethnography of SB RAS conducted a methodological seminar on March 4–5, 2019, that brought together archaeologists from Western and Eastern Siberia and the Far East. The workshop was attended by representatives of institutions of the Russian Academy of Sciences and executive authorities, as well as practicing archaeologists and experts. The extensive geography of the participants and the opportunity to communicate “at the same table” allowed us to openly discuss topical issues.
Results. The main topics of discussion were changes in the federal legislation related to the preservation of cultural heritage. The main issue here is enormous complexity of its adequate and full application at the local level. However, in some cases, efforts of regional executive bodies help to solve these problems quite effectively. The other side of the issue is preparation of proposals for a change in the regulatory documents governing such areas of the economy as forestry and subsoil use. The issue of systematizing information on cultural heritage sites, which is currently accumulated in various institutions, has acquired particular relevance. This is due to its colossal scale and increased interest in the results of analytical studies of the laws addressing spatial location of archaeological sites.
Conclusion. The outcome of the seminar was its resolution presented in this paper. The paragraphs of the resolution reflect the main conclusions and proposed solutions that were agreed by various specialists during the general discussion. This event, as a platform for communication, is extremely important for establishing a common position of the scientific archaeological community.
Hand-Held Firearms of Russian Warriors in Siberia at the End of the 16th – 17th Centuries (According to Tobolsk Archaeological Materials)
Authors: Adamov Aleksandr A. , Balyunov Igor V.
Published: May 2020

Purpose. Scientific knowledge about the military arsenal of Russian pioneers in Siberia is not complete. The archaeological materials of the town of Tobolsk allow us to enrich and specify available data on the armament of serving people.
Results. The study of firearms at the end of the 16th – 17th centuries has been based on an integrated approach using both written sources and archaeological materials. When analyzing findings, we widely use statistical calculation, classification and a comparative historical method. Our analysis of the bullets found on the territory of the town of Tobolsk shows that at the end of the 16th – 17th centuries one of mold features is a spherical lead projectile cast. However, there are bullets that are not fully cast. The lead funnel after casting is not always cut off from the bullet or is not completely cut off at all. On several findings, incisions were made that allowed to seriously wound the enemy, similar to the use of the lead funnel. Bullets were rarely made in a mechanical way, without casting. Among findings there are details of gun locks represented by screws from the percussion mechanism, flints and lead gasket. A separate category of findings are ramrod tips.
Conclusion. In Tobolsk at the end of the 16th – 17th centuries, wick guns gradually went out of use and were replaced by weapons with shock-flint locks. At the same time, both light carbines and pistols, and large-caliber muskets and fortress rifles had a limited distribution, and the most significant was the pishchal’ rifle. Tobolsk citizens tended to buy multipurpose weapons that could be used both for fighting and hunting, and those which were reasonably priced.
A Saber of the Kazakh Vali Khan from the Collection of the Moscow Kremlin Museums
Authors: Bobrov Leonid A. , Novoselov Vasily R.

Purpose. We describe a saber from the collection of the Moscow Kremlin Museums (Inventory no. 4427).
Results. The total length of the saber is 101.5 cm including the length of the blade 87.5 cm. When in the scabbard, the length is 106.5 cm. The grip and metal elements of the scabbard are made of gilded silver. Their surface is decorated with floral engraving. Mounts and big bezels contain pieces of turquoise and jade. The grip is inlaid with jade plates, gold and mounted rubies. We analyzed the construction and decoration of the saber and the scabbard and concluded that they were made by Ottoman masters in the first half of the 17th century. The closest analogues of the saber are stored in the Moscow Kremlin Armory, the State Hermitage Museum, the Metropolitan Museum of Art, etc. According to the inscription on the blade, we refer the weapon to the type of insignia, which were given to Kazakh rulers who became Russian citizens and were approved as khans. A common historiographical attribution of the saber as belonging to Erali Khan (1729) has been proved wrong. According to the documents of the 18th century available, the saber initially was to be given to a famous Kazakh khan of the Middle jüz of Kazakhstan Ablai Khan (1711–1780). In 1778, the blade of the 17th century was signed in Russian and Arab, the scabbard was covered with red tissue, the gilded elements were freshened up, and a shoulder harness made of silk of two colors was added, together with a case. In the second half of 1778, the saber was delivered to the Peter and Paul Fortress of the Novyi Ishim defense line, where it was to be handed to Ablai Khan. However, due to some political disagreements he refused to accept the signs of the power, and the saber, along with other gifts, was left to be stored in the fortress. In May 1781, Ablai’s son, a newly elected Vali Khan (1744–1821), addressed Russian authorities asking them to pass him the signs of the khan’s power and Ablai’s allowance. As the insignia was to be given to the new owner, the inscription had to be changed. The saber was sent to Orenburg, where a local master changed the khan’s name and the year. During an official ceremony in the Peter and Paul Fortress, which was held on 1 November, 1782, the weapon was awarded to Vali Khan. Later on, the saber was passed on and stored by some families of noble Kazakhs. Conclusion. The saber is of a high scientific value as it is the only surviving and almost undamaged symbol of Kazakh khans’ power. It is a unique relic of Russian-Kazakh relations in the 18th century.
A Summer Course on Siberian Archaeology for Foreign Students (2018, Students from the Republic of Korea)
Authors: Nesterkina Anastasiya L. , Kang In Uk
Published: May 2020

Purpose. Teaching Siberian archaeology to foreign students has its own characteristics and requires a special approach. Not all terms and phenomena are equivalent to the language and archaeological experience of the students. Therefore, the teacher is unlikely to be able to make foreign students interested in their subject matter by simply giving lectures, since it is not always possible to achieve a full contact with the audience. The use of visual materials while conducting courses helps solve a lot of problems of teaching Siberian archaeology to foreign students. In archaeology, such a visual material is an archaeological site or an artifact. Thus, the method of “immersion” into the environment of the subject studied, which we implement as an excursion to archaeological sites while giving lectures directly at the place where the studied phenomenon can be found, is particularly popular as a way of teaching archaeology to foreigners.
Results. Such a technique was implemented in 2018 by researchers of the Institute of Archaeology and Ethnography of SB RAS and Professor Kang In Uk during the summer course of teaching Siberian archaeology to history students from Kyung Hee University (Seoul, the Republic of Korea). As a part of this course, students visited mound complexes and rock art objects in the Altai Mountains and ground burial sites of the Neolithic and Bronze Age in the Baraba forest-steppe region. The course included not only a detailed examination of the sites, but also lecturing at each of them. As our experience shows, the students were most interested in the topics resembling the ancient culture of the peoples of the Korean Peninsula, such as burial mounds, rock images of female shamans, Andronovo-type objects, etc. These subjects are relevant not only for research theses, but also as topics for individual research projects. This indicates that the goal of hosting a summer course on archaeology of Siberia for Korean students was achieved: the topic arouses deep interest among the audience.
Conclusion. There is no doubt that the methodology of teaching Siberian archaeology to foreign students described in the present article is not only effective, but also has great prospects in the form of various master classes and workshops, as well as in the form of direct participation of foreign students in archaeological excavations in Siberia.
Photoredox Catalytic Trifluoromethylation and Perfluoroalkylation of (Hetero)arenes Using Trifluoroacetic and Related Carboxylic Acids
Authors: Yin Dehang , Su Dengquan , Jin Jian
Published: May 2020

A mild and practical method has been achieved that allows for the direct C–H trifluoromethylation, perfuoroalkylation and chlorodifluoromethylation of (hetero)arenes using inexpensive and abundant trifluoroacetic acid and the corresponding carboxylic acids. A diverse array of arenes and heteroarenes were successfully transformed into valuable fluoroalkylated compounds. The combination of photoredox catalysis and a diaryl sulfoxide provides a platform for the facile generation of fluoroalkyl radicals from the corresponding fluoroalkyl carboxylic acids under mild conditions.
ORF10: Molecular Insights into the Contagious Nature of Pandemic Novel Coronavirus 2019-nCoV
Authors: Mishra Dr. Seema
Published: May 2020

This article stems from the author's observations that ORF10, a protein with no sequence and structural conservation, provides with a high number of potentially immunogenic, promiscuous epitopes. With high degree of epitope conservation across CTL and HTL epitopes of ORF10, its existence in the 2019-nCoV genome is largely seen as particularly contributing to the highly contagious nature of this virus.

Precision antimicrobials that can kill pathogens without damaging host commensals hold potential to cure disease without antibiotic-associated dysbiosis. Here we report the de novo design of host defense peptides that have been rationally engineered to precisely target specific pathogens by mimicking key molecular features of the target microbe’s unique channel-forming membrane proteins, or porins. This biomimetic strategy exploits physical and structural motifs of the pathogen envelope, rather than targeting resistance-susceptible protein biochemical pathways, to construct fast-acting precision bacteriolytics. Utilizing this approach, we design an antitubercular sequence that undergoes instructed, tryptophan-zippered assembly within the mycolic-acid rich outer membrane of Mycobacterium tuberculosis (Mtb) to specifically kill the pathogen without collateral toxicity towards lung commensals or host tissue. These mycomembrane-templated mechanisms are rapid and synergistically enhance the potency of antibiotics that otherwise poorly diffuse across the rigid Mtb envelope, particularly those that exploit porins for antimycobacterial activity. This new porin-mimetic paradigm may serve as a conceptual basis for the directed design of new narrow-spectrum antimicrobial scaffolds.

Published: May 2020

In this work, we demonstrate that a novel post-treatment process that includes multi-step high-temperature annealing followed by high-power microwave oxygen plasma processing advantageously improves key properties for quantum technologies. We obtain single crystalline nanoparticles (NPs) of 100 nm diameter, presenting bulk-like inhomogeneous linewidths and population lifetimes (T1). Furthermore, a significant coherence lifetime (T2) extension, up to a factor of 5, is successfully achieved by modifying the oxygen-related point defects in theNPs by the oxygen plasma treatment. These promising results confirm the potential of these engineered RE NPs to integrate devices such as cavity-based single photon sources, quantum memories and processors. In addition, our strategy could be applied to a large variety of oxides to obtain outstanding crystalline quality NPs for a broad range of applications.
Predicting Ligand Binding Kinetics Using a Markovian Milestoning with Voronoi Tessellations Multiscale Approach
Authors: Jagger Benjamin , Ojha Anupam Anand , Amaro Rommie
Published: May 2020

Accurate and efficient computational predictions of ligand binding kinetics can be useful to inform drug discovery campaigns, particularly in the screening and lead optimization phases. Simulation Enabled Estimation of Kinetic Rates, SEEKR, is a multiscale molecular dynamics, Brownian dynamics, and milestoning simulation approach for calculating receptor-ligand association and dissociation rates. Here we present the implementation of a Markovian milestoning with Voronoi tessellations approach that significantly reduces the simulation cost of calculations as well as further improving their parallelizability. The new approach is applied to a host-guest system to assess its effectiveness for rank-ordering compounds by kinetic rates and to the model protein system, trypsin, with the noncovalent inhibitor benzamidine. For both applications, we demonstrate that the new approach requires up to a factor of 10 less simulation time to achieve results with comparable or increased accuracy.

Polymer thin films that emit and absorb circularly polarised light have been demonstrated with the promise of achieving important technological advances; from efficient, high-performance displays, to 3D imaging and all-organic spintronic devices. However, the origin of the large chiroptical effects in such films has, until now, remained elusive. We investigate the emergence of such phenomena in achiral polymers blended with a chiral small-molecule additive (1-aza[6]helicene) and intrinsically chiral-sidechain polymers using a combination of spectroscopic methods and structural probes. We show that – under conditions relevant for device fabrication – the large chiroptical effects are caused by coupling of electric and magnetic transition dipole moments (natural optical activity), not structural chirality as previously assumed, and may occur because of local order in a cylinder blue phase-type organisation. This disruptive mechanistic insight into chiral polymer thin films will offer new approaches towards chiroptical materials development after almost three decades of research in this area.
