Published: October 2021

In terms of current economic conditions, purchase and sale of goods is a key aspect of many enterprises’ activity. Thus, income generated to trading goods is an important financial and economic indicator of retailers by which one can understand if the goods sold comply with market demand. The efficiency of managerial decisions depends considerably on the financial information obtained through accounting. The article aims to study existing institutional practices and develop practical proposals for improving the accounting of goods. The methods of receipt and disposal of goods at trade enterprises were systematized. The forms of sale of goods, depending on the type of trade were revealed, which determines a certain specificity of accounting for the sale of goods. The principles of reflecting the obligations of retailers on off-balance sheet accounts for orders made through the online store were substantiated. Based on the study of documentation of operations for goods purchase, transportation, and storage, it has been defined that the requisites in primary documents are to identify the economic operation, on the basis of which the document is drawn up. Enterprises can elaborate independently their own forms of primary documents on the basis of standard forms provided their elaborated documents have all the obligatory requisites. The recommendations for improving the analytical accounting of sales of goods at trade enterprises were provided, the implementation of which will control and manage the sale of goods to increase the traded amount. In particular, based on the results of the analysis of accounting of trade enterprise liabilities, it has been proposed to represent the enterprise liabilities for online-store orders on the off-balance accounts (For example, to open subaccount 026 “Liabilities for Internet-store orders”). This approach will help represent the online sale of goods more completely and objectively as currently the Internet-realization of goods is one of the most popular forms of sales.

Published: October 2021

Статтю присвячено аналізу психолінгвістичних аспектів взаємодії психолога з учасниками бойових дій. Зазначено, що в науковій літературі традиційно використовується поняття «реабілітація», тобто повернення особистості на дотравматичний рівень без врахування отриманого досвіду, посттравматичного зростання та резилентності. Обґрунтовано доцільність вживання поширеного у англомовних країнах поняття резилентної реінтеграції, його психолінгвістичні особливості. Встановлено, що успішна адаптація учасників бойових дій до мирного життя визначається як резилентна реінтеграція – тобто продуктивність у різних галузях життя, зумовлена усвідомленням нових можливостей, набутих в результаті бойового досвіду. Ресурсами резилентної реінтеграції є копінг-стратегії, психологічне благополуччя, життєстійкість, посттравматичне зростання і резилентність. Проаналізовано бойові парадокси та їх вираз у мовленні учасників бойових дій, охарактеризовано можливості використання метафоричних карт задля полегшення комунікативної взаємодії з учасниками бойових дій та вербалізації ними психотравмуючих ситуацій. За результатами емпіричного дослідження встановлено, що переважна більшість учасників бойових дій є добре адаптованими (резилентно реінтегрованими, такими, що усвідомлюють цінність набутого на війні позитивного досвіду та використовують його у повсякденному мирному житті). Реінтегративні програми зазвичай спрямовані на такі галузі функціонування як осмислення сенсу життя, пошук нових життєвих цілей, формування міжособистісних стосунків зі значущими іншими, працевлаштування чи/та оволодіння новими професійними навичками, турбота про соматичне і психологічне здоров’я. Нами доведено, що використання метафоричних карт для роботи із психотравмою є ефективним інструментом комунікації психолога з учасниками бойових дій, оскільки дозволяють вербалізувати їх травматичний досвід та мінімізувати бар’єри при спілкуванні з фахівцями, водночас останнім слід враховувати наявність бойових парадоксів, що виявляються в усному мовленні учасників бойових дій та деталізувати кожен вислів, зокрема використовуючи для цього метафоричні асоціативні карти чи інші засоби експресивної терапії.
Ключові слова: адаптація, учасники бойових дій, ПТСР, копінг-стратегії, посттравматичне зростання, резилентна реінгтеграція.

Authors: Чиханцова Олена
Published: October 2021

У статті висвітлюються опис та апробаційні результати комплексної програма психологічного забезпечення розвитку життєстійкості особистості засобами позитивної психотерапії, яка складається з трьох блоків і є розвиваючою психолого-терапевтичною програмою.
Показано, що особистісні ресурси можуть бути представлені як система здібностей людини до усунення протиріч особистості з життєвим середовищем, подолання несприятливих життєвих обставин за допомогою засобів позитивної психотерапії. Інакше кажучи, особистісні ресурси виступають як характеристика особистості, яка забезпечує особистості можливість долати важкі життєві ситуації. Тому досить актуальним напрямком в дослідженні психологічних ресурсів є вивчення їх структури, механізмів функціонування, динамічних характеристик, а також розробка тренінгових програм, де позитивна психотерапія виступає фактором розвитку життєдіяльності особистості.
Зазначено, що тренінг життєстійкості заснований на припущенні, що життєстійкість не є вродженою якістю, а формується протягом життя. Це система переконань, яка може бути розвинена. Для пoбудoви тренінгoвoї прoграми ми базувались на принципаx групoвoї рoбoти. Тренінг проводився зі студентами-бакалаврами денної форми навчання кафедри психології Інституту соціальних технологій Університету «Україна» та тривав 10 тижнів, протягом яких було проведено 5 занять по 6 годин.
Встановлено, що учасники тренінгу надали достатньо високі бали, що вказує на те, що тренінг для них був такий, що має важливу тему, містить нову інформацію, є практично значущим, насиченим та послідовним. Визначено, що розроблена програма психологічного забезпечення життєстійкості особистості позитивно позначається на всіх складових життєстійкості. Усі показники життєстійкості особистості підвищились.
Ключові слова: життєстійкість особистості, позитивна психотерапія, особистісні ресурси, актуальні здібності.
Relationship between personal values and adaptation of students: transfer of the method of "learning by action"

Published: October 2021

The article reveals the relationship between personal values and adaptation of students in the transfer of the method of "learning by doing". It is shown that the value of creativity in the stable component was associated with maladaptation, and in the dynamic on the contrary, which indicates that respondents are able to show creativity when needed, "here and now", ie in critical situations. Contradiction is observed in the professional component with the importance of the value of spiritual satisfaction - material well-being. That is, if the team or the environment of the respondents are dominated by spiritual values (morality, morality, belief in the good), the process of adaptation will be faster and easier, and if the material (money, benefits), the adaptation is difficult. This may indicate altruism and selflessness. Values have been shown to play an important role in the adaptation process. Regarding the constituent values, both dynamic and stable components are important. Of particular importance is the experience of transferring the method of "Learning by Action" (Service Learning) in higher education institutions. This method belongs to the methods of education in the interests of sustainable development and involves the integration into the educational process of higher education institutions of social activity of students. The effectiveness of the method is that students of higher education institutions who have experienced volunteer work in social projects in the educational process are more prepared in practical terms for the labor market and are able to see the meaning of activities in various social institutions. The main goal is to develop students' social responsibility and other key competencies through the use of the "Learning by Action" method.

Authors: Lakina N. , Doluda V. , Matveeva V. , Sidorov A. , Rabinovich G.
Published: October 2021

To modify graphite electrodes with a conductive enzyme polymer matrix, the method of drip application of a liquid polymer solution of various compositions was used: polyvinylpyrrolidone (40%), chitosan (0.1%), glutaric dialdehyde (0.1%), glucoxidase and peroxidase in a ratio of 2:5. To assess the effect of the immobilization time (x1), the pH of immobilization (x2) and the enzyme/carrier ratio (x3) on the activity of the enzyme electrodes, a three-factor and three-level Box-Benken and RSM design was used. This model was able to adequately predict the results of immobilization within the range of variables used. The most favorable conditions and the largest number of molecules of the enzyme complex are in the electrochemically active state when they are immobilized on PVP using modifying agents chitosan and glutaraldehyde. The results demonstrate that the productivity of the enzymatic biofuel element is directly proportional to the activity of the immobilized GOX/HRP complex, since in this case the glucose oxidation reaction can proceed more efficiently.

Published: October 2021

This paper reviews taxonomy, importance and diseases of pepper plants belonging to Capsicum genus. Five species of the genus are domesticated, Capsicum annuum being the most cultivated species followed by C. chinense and C. frutescens while C. baccatum and C. pubescens are grown in limited areas of some regions. Review of the available literature data has shown that more than 122 species of microorganisms can cause pepper diseases, including >58 species of fungi, 11 oomycetes, 15 bacteria, 32 viruses, > 6 species of nematodes, and some higher parasitic plants. From these 18 species of fungi, 2 oomycetes, one bacterium, two viruses, one root-knot nematode, two species of each of dodder and broomrape have been recorded in Uzbekistan. However, all of these organisms but one powdery mildew fungus has been registered on other than pepper plants. Previously the authors of the current paper have found that deadly crown rot of both sweet and hot peppers caused by Fusarium oxysporum (supposedly f. sp. radici-capsici) occurred widely in six districts of Uzbekistan.

Law and Nigeria's Development: How to Strengthen the Efficacy of Law for Development in Nigeria
Authors: Saredau Daniel Philemon
Published: October 2021

In today's world, the role of law transcends the maintenance of social order and administration of justice. Law has a crucial role to play in the developmental processes of states. Nigeria, a country now reputed to be the poverty capital of the world, is in dire need of development. Law can aid Nigeria's quest towards development. This study addresses the question what is development and makes an attempt to offer a holistic notion of the concept. In appraising the relevance of law in Nigeria's developmental process, the study examined instances where the law was employed to enable development, either through the facilitation of indices of development or through the inhibition of impediments to development. Additionally, the study interrogated the nexus between the law and development policy in Nigeria, and appraised the role of law in Nigeria's development process. Prescriptively, the study suggested ways in which the relevance of law in Nigeria's development process can be supplemented, namely prioritisation of the development question in law-making, execution and interpretation; promoting the realisation of socio-economic rights; and the mainstreaming of customary law as an integral part of the law and development discourse.
The Troubling Shortcomings of International Asset Freezes: The Hunt for Gaddafi's Lost Billions
Authors: Pavlidis Georgios
Published: October 2021

Although international asset recovery is one of the key anti-corruption commitments under the United Nations Convention against Corruption and the African Union Convention on Preventing and Combating Corruption, a huge gap remains between commitments and implementation. The shortcomings of international asset freezes in the case of Libya, with billions of dollars unaccounted for, confirm this statement. In this article, I identify the major obstacles for recovering stolen assets in the case of Libya and I argue that the international community needs to enhance asset recovery and mutual legal assistance, as well as to explore bold ideas, such as the reversal of the burden of proof as to the illicit origin of the assets.

In this article is being reviewed different approaches to optimize data exchange in a network using cryptography - to make any date secure, compression - to make any data smaller and accelerated routing, which is based on meta information about target destination: how far they are, how loaded they are. The object of research is the process of data exchange in the network. The purpose of the study is to optimize the process of data exchange in the network in order to improve the security and speed of data transfer. Research methods - statistical analysis of data transmission efficiency indicators. When transmitting data, cryptographic algorithms are used to ensure integrity and security, these algorithms allow the exchange of data using public and private key technology. But now this may not be enough to complicate the process of decrypting the data, it is advisable to make the messages transmitted between nodes as similar as possible to each other, for example, the same length. This solution will minimize the possibility of revealing the cipher by analysis for the attacker, but at the same time significantly increases the volume of transmitted messages due to the additional «masking» amount of data. To compensate for this effect in high-load networks, it is proposed to use a smart routing algorithm, which allows you to choose the optimal route for messages, taking into account the load of routers and channels between them.

Published: October 2021

Ibe aim of this work is to study the nature of the conductivity of melts of iron chalcogenides (Fe-Se, Fe-Te, FeS-Na2S) and the conditions of its possible transformation in order to bring the high-conductivity melt to a state suitable for electrolytic decomposition into metal and chalcogen. To solve this problem, a set of methods was used - electrical conductivity (ж), thermo-EMF (a), polarization characteristics (І-V) and electrolysis (n). ж of high-conductivity melts was investigated by the four-probe method on a direct current in a quartz U-shaped cell of capillary type with graphite electrodes and molybdenum current leads in the direct current mode. The systematic error due to the accuracy class of the devices is 1%; random - does not exceed 1%. Low ж melts were studied by the two-probe AC method. Due to the high chemical aggressiveness of FeS-Na2S melts, a measuring cell with an alundum capillary was developed. Random error when measuring ж two-probe method on alternating current is 3%, systematic - is within 2%. Thermo-EMF was measured by the differential method with respect to tungsten probes. The temperature difference between the probes was recorded by a differential thermocouple. Systematic error in measuring thermo-EMF was 2%, random - 1.5%. Polarization characteristics were removed by the method of direct current in a simple cell without separation of electrode spaces. In cells of this type in an argon medium over the melt and experiments on electrolysis were performed. It is established that all samples are characterized by significant values of electrical conductivity (of the order of thousands of Sm/cm) and its negative temperature coefficients; the absolute thermo-EMF of all samples is units of цУ/deg. Melts are qualified as electron-ion (polyfunctional) conductors with a predominant metallic contribution to the conductivity. The introduction of Na2S into the FeS melt leads to a decrease in electrical conductivity and the transformation of its temperature dependence to the inherent ionic compounds. The melt electrolysis of the FeS-Na2S system with the production of iron was carried out. Thus the possibility of transformation of the nature of conductivity of highly conductive chalcogenide melts of iron towards their electrolytic ability is proved. The obtained results must be taken into account when using electrochemical technology of processing polymetallic sulfide ores, which include metal chalcogenides of iron family.

Published: October 2021

The article considers automated traffic flow control systems, their classification and description. Based on the above, it can be argued that traffic control systems have the characteristics of distributed, discrete and non-stationary complex systems used to solve traffic control problems by modern means of information and computer technology. The object of research is to improve traffic control with the help of automated control systems Purpose - analysis of automated traffic management systems With the rapid growth of the car fleet, there is an overload of the street and road network of cities. Even today, the street and road network does not meet the requirements for the organization and safety of road traffic. A survey of traffic flows shows that the road network operates at the capacity limit, and in some places exceeds this limit. The main reason for this transport situation in cities is the mismatch between the level of motorization and the density of the road network. Therefore, to improve, improve traffic control, it is proposed to use automated traffic management systems. But first you need to analyze them in detail. It is noted that the efficiency of the street and road network depends entirely on the effective balanced operation of all its elements.

This article considers the use of the mathematical apparatus of the theory of games with nature to model such a socio-economic phenomenon as the process of international freight transportation when performing delivery by own and borrowed vehicles on Kyiv-Warsaw route. Calculations are made with the use of existing costs and tariffs for the selected direction of transportation. The object of research is the process of international freight transportation management. The purpose of the work is to study the peculiarities of decision-making with the use of mixed strategies. The research method is the theory of statistical decisions, namely the theory of decision-making in the conditions of playing with nature. The player, i.e. the person who will make the decision, is the company that performs the carriage of goods by road in international traffic and is fully responsible for organizing the process of delivery of goods by road on the route. The situation is modeled using variants of various demand for transportation. This demand acts as the uncertainty of different variations of nature's strategies. Recommendations are given for the application of four decision making criteria: Wald, Savage, Laplace and Hurwitz criteria. Appropriate calculations were performed and the obtained results were commented on, because each criterion offers a new solution to a given situation. Calculations of application of mixed strategies are presented in the Excel spreadsheet.

ANALYSIS OF THE MECHANISM OF REINFORCEMENT OF THE ROAD STRUCTURE WITH A UNLOADING SECTION
Authors:   National Transport University, Kyiv, Ukraine, L Shevchuk
Published: October 2021

The problem posed is about the mechanism for reinforcing the road structure with a slab with an unloading cut. The reasons for the appearance of transverse cracks in the upper layer of the road surface in winter have been investigated. Solvable equations are formulated, their finite element analogs are constructed. Cases of loads at different values of elastic module and plate sizes are considered. At low temperatures, the upper layers of the road try to reduce their length, however, due to their almost infinite length, they cannot do this and transverse disordered cracks appear in the upper layer, which, due to the action of transport loads and the forces of frozen water, lead to further delamination and destruction of the road structure. Therefore, the introduction into another layer of a reinforced slab made of a stiffer and more durable material that is capable of absorbing increased stresses allows the upper layer to shorten and lengthen freely and removes the arising longitudinal thermal stress. Due to the fact that this plate is located in the zone of stress concentration, these stresses become less dangerous.

Published: October 2021

The paper investigates the value paradigm of Ukrainians and their peculiarities by means of the theory of spiral dynamics, analyzes the index of perception of corruption in different countries of the world and identifies the relationship between high level of corruption and low level of income, and designs inclusive growth and development of Ukraine. Object of study – the processes of inclusive growth and development through the prism of the valueoriented approach of the theory of spiral dynamics. Purpose of the study – to substantiate the prerequisites for the formation of a model of inclusive development based on the theory of spiral dynamics, which will allow to involve all members of society in socio-economic processes, taking into account their values, needs and opportunities. Method of the study – methods of economic, systemic, comparative analysis. Results and innovation of the study – in the paper investigates the influence of the system of values of society on its socio-economic development with the help of the theory of spiral dynamics, peculiarities of its evolution and influence on the socio-economic development of the country. The mental features of the Ukrainians, their evolution and prerequisites for mental modernization through the change of the paradigm of thinking through the construction of an inclusive state are analyzed. The article proposes a design for inclusive growth and development based on four main pillars: rules, institutions, a well-informed society, and political leadership. Modern IT technologies will become a tool for implementing this model. The modern paternalistic ideology that underlies the state centralization of financial resources with further redistribution should be changed to the ideology of promoting entrepreneurship and private initiatives, which will undoubtedly improve the well-being of all citizens and make our country competitive in the global arena.

The article is devoted to a comprehensive study of theoretical and methodological principles, scientific and practical approach to the use of outsourcing in national economic systems in the implementation of modern unstable, risky economic relations. The productive use of outsourcing is an organic component of the global process of intellectual production capital, which is realized mainly through international cooperation in the context of internationalization of production and exchange. These interconnected economic processes in the modern world unfold in a globalized market environment and are characterized by increased importance of various forms of division of labor, the growth of economic and organizational-economic interdependence of economic systems of different countries and international economic organizations. Internationalization, openness of economies determine social progress for all countries through the manifestation of the implementation of outsourcing services in global business relations. The object of research is to find out the advantages and potential of outsourcing on the basis of long­term experience of foreign countries in Ukraine. Research methods - scientific abstraction, statistical, analytical, logical-dialectical, empirical research. Analysis and comparison of a significant number of works on scientific substantiation and practical experience of using international outsourcing in the context of globalization by business companies to address topical issues of its implementation in the global market environment based on a number of positive and negative factors, incompletely received a competent assessment. The set of interpretations of outsourcing as a modern cooperative form of business relations in joint ventures is studied, the key determinants of intensification of outsourcing relations are clarified, the tendencies of their realization as a result of globalization processes are analyzed. A number of organizational and economic processes, models that can positively affect the quality of dynamic development of outsourcing are identified. There are also clarifications and a number of advantages of promoting the practice of its use. The peculiarities of the use of outsourcing services in the production process using the latest technologies through electronic information resources, the provision of services of various levels in developed market economies, as well as the problems of using outsourcing in the domestic economy. A number of proposals for the objective feasibility of implementing this type of cooperation to ensure high rates of activity of domestic business companies of various forms of ownership, production and services.

Published: October 2021

The object of research - the development of transport infrastructure of EU countries, trends, prerequisites for successful implementation. The purpose of the work is to study the experience of implementing transport infrastructure development projects on the basis of public-private partnership in the countries of the European Union. The results of the study will be used to form an information base on transport infrastructure development projects that have been implemented on the basis of public-private partnership. Relevant information will be used to compare the expected performance of domestic projects with similar projects in the European Union The research method is monographic and statistical. The article is devoted to the study of trends in the application of the mechanism of public-private partnership in the development of transport infrastructure of the European Union. It was found that since 2013, the volume of investment and the number of projects implemented on the basis of PPP, tend to decrease. Thus, compared to 2013, the amount of capital invested in 2019 decreased by more than 50%. The transport infrastructure consistently ranks first among the sectors of the economy in terms of investments made on the basis of partnership between the state and private business. At the same time, the leaders of investments in PPP projects are such countries as Great Britain, France and Germany. According to the number of implemented projects - France, Great Britain and Belgium. Appropriate preconditions must be created for the effective implementation of PPP projects. Further areas of research are the study of programs, policies and practices used by other countries that actively involve the private sector in the provision of transport infrastructure services; development of relevant recommendations for the implementation and improvement of Ukraine's policy and practice in the field of transport infrastructure development.

Att utveckla förmågan att reflektera om sin yrkespraktik
Authors: Nyberg Malin , Thorsten Anja
Published: October 2021

Reflektionsuppgifter av olika slag är viktigt på många yrkesprogram. Genom reflektionen förväntas eleverna analysera sina erfarenheter och koppla samman teori och praktik. På så sätt kan de utveckla en begynnande yrkesidentitet. Att reflektera kan dock vara en utmaning för många elever. Den här artikeln bidrar med kunskap både om hur eleverna gör när de reflekterar och om vad lärare skulle behöva lyfta fram i undervisningen för att stötta elevernas reflektionsförmåga.
Mathematical Modeling of Zebrafish Social Behavior in Response to Acute Caffeine Administration
Authors: Tuqan Mohammad , Porfiri Maurizio
Published: October 2021

Zebrafish is a model organism that is receiving considerable attention in preclinical research. Particularly important is the use of zebrafish in behavioral pharmacology, where a number of high-throughput experimental paradigms have been proposed to quantify the effect of psychoactive substances consequences on individual and social behavior. In an effort to assist experimental research and improve animal welfare, we propose a mathematical model for the social behavior of groups of zebrafish swimming in a shallow water tank in response to the administration of psychoactive compounds to select individuals. We specialize the mathematical model to caffeine, a popular anxiogenic compound. Each fish is assigned to a Markov chain that describes transitions between freezing and swimming. When swimming, zebrafish locomotion is modeled as a pair of coupled stochastic differential equations, describing the time evolution of the turn-rate and speed in response to caffeine administration. Comparison with experimental results demonstrates the accuracy of the model and its potential use in the design ofin-silicoexperiments.

We seek to use dimensionality reduction to simplify the difficult task of controlling a lower limb prosthesis. Though many techniques for dimensionality reduction have been described, it is not clear which is the most appropriate for human gait data. In this study, we first compare how Principal Component Analysis (PCA) and an autoencoder on poses (Pose-AE) transform human kinematics data during flat ground and stair walking. Second, we compare the performance of PCA, Pose-AE and a new autoencoder trained on full human movement trajectories (Move-AE) in order to capture the time varying properties of gait. We compare these methods for both movement classification and identifying the individual. These are key capabilities for identifying useful data representations for prosthetic control. We first find that Pose-AE outperforms PCA on dimensionality reduction by achieving a higher Variance Accounted For (VAF) across flat ground walking data, stairs data, and undirected natural movements. We then find in our second task that Move-AE significantly outperforms both PCA and Pose-AE on movement classification and individual identification tasks. This suggests the autoencoder is more suitable than PCA for dimensionality reduction of human gait, and can be used to encode useful representations of entire movements to facilitate prosthetic control tasks.

Lysine lactylation has been recognized as a novel post-translational modification occurring on histones. However, lactylation in non-histone proteins, especially in proteins of early branching organisms, is not well understood. Energy metabolism and the histone repertoire in the early diverging protozoan parasite Trypanosoma brucei, the causative agent of African trypanosomiasis, markedly diverge from those of conventional eukaryotes. Here, we present the first exhaustive proteome-wide investigation of lactylated sites in T. brucei. We identified 387 lysine-lactylated sites in 257 proteins of various cellular localizations and biological functions. Further, we revealed that glucose metabolism critically regulates protein lactylation in T. brucei although the parasite lacks lactate dehydrogenase. However, unlike mammals, increasing the glucose concentration reduced the level of lactate, and protein lactylation decreased in T. brucei via a unique lactate production pathway. In addition to providing a valuable resource, these foregoing data reveal the regulatory roles of protein lactylation of trypanosomes in energy metabolism and gene expression.

An extensive body of literature suggested a possible role of the microtubule-associated protein Tau in chromatin functions and/or organization in neuronal, non-neuronal, and cancer cells. How Tau functions in these processes remains elusive. Here we report that Tau expression in breast cancer cell lines causes resistance to the anti-cancer effects of histone deacetylase inhibitors, by preventing histone deacetylase inhibitor-inducible gene expression and remodeling of chromatin structure. We identify Tau as a protein recognizing and binding to core histone when H3 and H4 are devoid of any post-translational modifications or acetylated H4 that increases the Tau’s affinity. Consistent with chromatin structure alterations in neurons found in frontotemporal lobar degeneration, Tau mutations did not prevent histone deacetylase-inhibitor-induced higher chromatin structure remodeling by suppressing Tau binding to histones. In addition, we demonstrate that the interaction between Tau and histones prevents further histone H3 post-translational modifications induced by histone deacetylase-inhibitor treatment by maintaining a more compact chromatin structure. Altogether, these results highlight a new cellular role for Tau as a chromatin reader, which opens new therapeutic avenues to exploit Tau biology in neuronal and cancer cells.
