Watermarking is a today's digital hiding technique within certain electronic content: for example, message, image, video, or audio recordings. Recent times, it was created as a modern copyright security tool. The pattern in zero watermarking technique isn't really inserted directly in the cover image, but has a logical relation with that cover image. In this article, we propose a powerful convolution neural Networks (CNN) and deep learning algorithm-based-watermarking technique in which the CNN produces robust inherent selected features and is merged with the XOR activity of host's watermark sequence. The outcomes of our proposed method present the courage of the watermark counter to many typical image processing techniques.

Work Place Ergonomics- A Review
Authors: Omeshree Nagrale
Published: February 2021

Ergonomics is the study of the interaction between people and machines and the factors that affect the

interaction. Its purpose is to improve the performance of systems by improving human machine interaction.

This can be done by ‘designing-in’ a better interface or by ‘designing-out’ factors in the work environment, in

the task or in the organization of work that degrade human–machine performance. Systems can be improved

by • Designing the user-interface to make it more compatible with the task and the user. This makes it easier

to use and more resistant to errors that people are known to make. • Changing the work environment to

make it safer and more appropriate for the task. • Changing the task to make it more compatible with user

characteristics. • Changing the way work is organized to accommodate people’s psychological and social

needs. This article presents on overview on current knowledge on work place ergonomics.

Trong giai đoạn cả thế giới cùng chung tay hợp sức đẩy lùi sự lây lan của COVID-19, nhiều biện pháp phòng chống dịch bệnh chưa từng có đã và đang được thực hiện khắp nơi trên thế giới, trong đó có cả Việt Nam. Người dân nước ta đang phản ứng như thế nào đối với mối đe dọa đến sức khỏe và tính mạng của họ? Để trả lời câu hỏi này, bài nghiên cứu của chúng tôi mong muốn tìm hiểu hành vi thực hiện các biện pháp phòng chống dịch bệnh của người dân Việt Nam, và đặc biệt là đi sâu hơn về các nhân tố có thể tác động đến vấn đề này. Thông qua 1798 mẫu khảo sát trực tuyến được thu thập trong ba ngày cuối cùng của giai đoạn thực hiện giãn cách xã hội trên phạm vi toàn quốc vào giữa tháng 4, kết quả nghiên cứu cho thấy, ba yếu tố ảnh hưởng đến hành vi phòng chống dịch bệnh của người dân bao gồm: giới tính, kiến thức cơ bản về COVID-19 và biện pháp phòng ngừa, và thái độ đối với các chính sách của Nhà nước về phòng chống dịch. Chúng tôi còn phát hiện rằng: Nam giới thực hiện phòng chống dịch bệnh kém hơn nữ giới; Người tích lũy kiến thức về COVID-19 càng nhiều thì việc thực hiện phòng chống dịch bệnh của họ chưa chắc càng tốt. Để có thể đưa ra biện pháp tốt nhất cho việc kiểm soát COVID-19 ở nước ta, chúng tôi kiến nghị nên có thêm nhiều nghiên cứu về các yếu tố ảnh hưởng hành vi phòng ngừa dịch bệnh của người dân, nhằm cung cấp thêm những thông tin hữu ích cho chính quyền, các nhà hoạch định chính sách y tế công cộng và nhân viên y tế.

The Arctic zone of the Russian Federation (AZRF) is characterized by the fragility of the ecosystem, the slightest violation of which can lead to catastrophic negative consequences on a global scale. Due to the availability of production facilities of various scales and environmental safety classes within the territorial and aquatic Arctic, the risk of negative impact on the environment is very significant. In order to prevent possible environmental damage within the AZRF, it is advisable to carry out activities related to the implementation of continuous monitoring of the environment aimed at detecting sources that pose a potential threat to the ecosystem. Taking into account the harsh Arctic climate, the lack of the possibility of year-round land access to industrial facilities located in the Russian Arctic, the scale and peculiarities of the implementation of Arctic offshore projects for the extraction and processing of hydrocarbons, the length and congestion of the used logistic artery - the Northern Sea Route, the choice of means, which are used for monitoring the ecological situation is justified by their mobility and efficiency. In particular, such means include technologies that allow remote monitoring of the environmental situation of industrial facilities. The article outlines the role of remote methods of environmental monitoring and control in the system of environmental protection measures of the Russian Arctic, presents methods for assessing the impact of industrial facilities of the oil and gas complex (OGC) on the environment of the Russian Arctic, presents the results of assessing the effectiveness of using remote methods of environmental monitoring of industrial facilities for the production and processing of hydrocarbons (HC) in the AZRF. The scientific novelty of the study lies in the substantiation of the ecological and economic feasibility of using the methods of remote monitoring of the ecological situation in the Arctic.

CHOICE OF TACTICS OF SURGICAL TREATMENT OF VARICOSE DISEASE DEPENDING ON THE VARIANT OF THE ANATOMICAL STRUCTURE OF SAPHENO-POPLITEAL ANASTOMOSIS IN DOPPLEROMETRY OF THE VENES OF THE LOWER LIMBS
Authors: Babinkina I. B. , Novikova G. A. , Babinkina G. P.
Published: February 2021

Summary. The aim of the study is to determine the variants of the anatomical structure of the saphenopliteal anastomosis in ultrasound Doppler of the veins of the lower extremities, including as sources of pathological blood reflux in varicose veins of the small saphenous vein basin, and the importance of insolvent veins in the formation of insufficiency in the small saphenous vein basin to clarify the further protocol treatment.

Materials and methods. The venous system of 2348 patients was studied, including both patients with various pathologies of the venous system, including those with varicose veins, and those in whom the pathology of the veins was not detected by USDG.

Results and discussion. In patients with USDG, various anatomical variants of the structure of the sapheno-popliteal anastomosis were found. The anastomosis may look like a perforating vein and have a fairly sharp angle of deviation from the trunk. In these cases, it is recommended to conduct an open surgical intervention, namely: crossectomy — ligation and transection of the small saphenous vein, striping — removal of the trunk of the small saphenous vein, ligation of insolvent communicative veins, miniflebectomy - removal of varicose nodes through punctures. The smooth course of the sapheno-popliteal anastomosis was found in 58.0 % of the subjects and did not depend on the level of the anastomosis. In such cases, the option of choice for surgical intervention was minimally invasive technologies: laser coagulation, radiofrequency ablation, as well as combined phlebectomy, which includes the following stages - removal of varicose inflows of the small saphenous vein and elimination of incompetent perforating veins. Indirect variants of the anastomosis turned out to be frequent, for example, through the sural or nonsaphenic vein with the presence of additional venous vessels (up to 18.0 % of those studied). In these cases, the level of the anastomosis was also formed below the knee joint gap. According to the USDG data, the anatomical absence of the sapheno-popliteal anastomosis was found only in 142 patients, which is less than 1.0 %. In such patients, a search and elimination of pathological reflux is performed, which leads to the development of varicose veins in the system of the small saphenous vein. Its varicose inflows are removed and insolvent perforating veins are eliminated.

Conclusion. The specialists’ understanding of the variants of the structure of the saphenopliteal anastomosis in normal and pathological conditions, as well as the observance of the full examination protocol for venous ultrasonography, allows providing detailed information in order to determine the most effective treatment tactics and prevention of disease recurrence.

British Intellectuals and the British Government: Junius vs Grafton Administration (1768–1770)
Authors: Сидоркина Т.С.
Published: February 2021

В статье рассматривается процесс развертывания борьбы известного анонимного публициста Юниуса с администрацией герцога Графтона с ноября 1768 года по январь 1770. Издатель журнала “The Public Advertiser”, в котором печатались письма Юниуса, в 1772 году опубликовал их и ответы некоторых оппонентов анонимного автора в сборнике “Stat Nominis Umbra”, оставив широкое поле для исследований будущим поколениям историков. «Письма Юниуса» до сих пор не переведены на русский язык. Это объясняется, с одной стороны, трудностями интерпретации иносказательности текста, с другой — сложностью исторического контекста, связанного с ситуацией политического кризиса в Британии на рубеже 60–70-х годов XVIII века. В статье на основании текста писем Юниуса реконструирован персональный состав кабинета герцога Графтона, обстоятельства прихода его к власти, а также показана слабость правительства в решении двух принципиально важных вопросов этого периода — дело Уилкса и кризис в английских североамериканских колониях. Кульминацией карьеры Юниуса является письмо XXXV, в котором анонимный автор посмел обратиться к самому Георгу III и попытаться навязать ему свои советы. После этого в январе 1770 года герцог Графтон подает в отставку, оставив тем самым в победителях своего главного политического соперника.

The article focuses on the confrontation between an anonymous publicist known to the general public as Junius and the Duke of Grafton, the prime minister of the United Kingdom. The confrontation started in November 1768 and finished in 1770. The anonymous writer Junius contributed his public letters to the Public Advertiser, a London newspaper which later, in 1772, published the letters and some answers of Junius’ opponents in the Letters of Junius: Stat Nominis Umbra. The book, which contains valuable historical information, remains untranslated into Russian. Its allegorical and figurative language makes
the book highly difficult to translate. Moreover, it is exceptionally difficult to render in translation the intricacies of the historical background, namely of the political crisis Britain was involved in at the turn
of the 1760s–1770s. The article analyzes the letters of Junius to reconstruct the cabinet composition and
the circumstances of the Duke of Grafton’s rise to power. The analysis shows that the Grafton ministry failed to solve two crucial problems of the time, namely the Wilkes case and the crisis in Britain’s North American colonies. The turning point in Junius’ career was his letter XXXV, in which he addressed
the prime minister himself and sought to impose his advice on the 3rdDuke of Grafton. After that in January 1770, the Duke of Grafton resigned from his post recognizing defeat from his major political adversary.

A base teórica que sustenta a pesquisa é fornecida pelos estudos de Carrano (2007), de Freire (1987), de Andrade (2006) e de Arroyo (2017). No trabalho, foi possível constatar que o número de alunos com a idade de 15 a 19 anos matriculados na EJA é alto. As causas para a juvenilização são muitas, porém, a principal é a reprovação em outras modalidades educacionais, que também está relacionada às implicações pedagógicas, além dos problemas vividos fora da escola. Diversas alterações se tornam imperativas na organização pedagógica da EJA, mas a pesquisa aponta e dá destaque para a urgência de mudanças no currículo.

Contribution of Magnetic Reconnection Events to Energy Dissipation in Space Plasma Turbulence
Authors: Hou Chuanpeng , He Jiansen , Zhu Xingyu , Wang Ying
Published: February 2021

By analyzing the magnetosheath measurements from the Magnetospheric Multiscale Spacecraft, we obtain statistical results for the contribution of magnetic reconnection (MR) events at electron scales to the energy dissipation of coherent structures in shocked turbulent plasmas. The partial variance of increments (PVI) method is employed to find coherent structures in the magnetic field data. We consider criteria to further identify MR events, such as reversal of magnetic field components, significant energy dissipation, and evident electron outflow velocity. Statistically, for most MR events, their PVI values are larger than those of other types of coherent structures, and their energy dissipations are also stronger. However, due to the relatively small number of MR events, their contribution to coherent structures’ energy dissipation is relatively trivial. If the dissipation of non-coherent structures is taken into account, MR’s contribution to energy dissipation would be even less. Hence, we suggest that MR events, though having strong dissipation locally, are not the major contributor to energy dissipation in the turbulent magnetosheath. After analyzing the features of non-MR current sheets, we propose that these are mainly coherent structures inherent to kinetic Alfvén fluctuations.

We present Atacama Large Millimeter/submillimeter Array [C ii] 158 μm line and far-infrared (FIR) continuum emission observations toward HSC J120505.09−000027.9 (J1205−0000) at z = 6.72 with a beam size of ∼0.″8 × 0.″5 (or 4.1 kpc × 2.6 kpc), the most distant red quasar known to date. Red quasars are modestly reddened by dust and are thought to be in rapid transition from an obscured starburst to an unobscured normal quasar, driven by powerful active galactic nucleus (AGN) feedback that blows out a cocoon of interstellar medium. The FIR continuum of J1205−0000 is bright, with an estimated luminosity of L
FIR ∼ 3 × 1012
L
⊙. The [C ii] line emission is extended on scales of r ∼ 5 kpc, greater than that of the FIR continuum. The line profiles at the extended regions are complex and broad (FWHM ∼ 630–780 km s−1). Although it is not practical to identify the nature of this extended structure, possible explanations include (i) companion/merging galaxies and (ii) massive AGN-driven outflows. For the case of (i), the companions are modestly star-forming (∼10 M
⊙ yr−1) but are not detected by our Subaru optical observations (y
AB,5σ
= 24.4 mag). For the case of (ii), our lower limit to the cold neutral outflow rate is ∼100 M
⊙ yr−1. The outflow kinetic energy and momentum are both much lower than predicted in energy-conserving wind models, suggesting that the AGN feedback in this quasar is not capable of completely suppressing its star formation.

Published: February 2021

We present a comprehensive investigation of main-sequence binaries in the DRAGON simulations, which are the first one-million-particle direct N-body simulations of globular clusters. We analyze the orbital parameters of the binary samples in two of the DRAGON simulations, D1-R7-IMF93 and D2-R7-IMF01, focusing on their secular evolution and correlations up to 12 Gyr. These two models have different initial stellar mass functions: Kroupa 1993 (D1-R7-IMF93) and Kroupa 2001 (D2-R7-IMF01); and different initial mass-ratio distributions: random paring (D1-R7-IMF93) and a power law (D1-R7-IMF93). In general, the mass ratio of a population of binaries increases over time due to stellar evolution, which is less significant in D2-R7-IMF01. In D1-R7-IMF93, primordial binaries with a mass ratio q ≈ 0.2 are most common, and the frequency linearly declines with increasing q at all times. Dynamical binaries of both models have higher eccentricities and larger semimajor axes than primordial binaries. They are preferentially located in the inner part of the star cluster. Secular evolution of binary orbital parameters does not depend on the initial mass-ratio distribution, but is sensitive to the initial binary distribution of the system. At t = 12 Gyr, the binary fraction decreases radially outwards, and mass segregation is present. A color difference of 0.1 mag in F330W − F814W and 0.2 mag in NUV − y between the core and the outskirts of both clusters is seen, which is a reflection of the binary radial distribution and the mass segregation in the cluster. The complete set of data for primordial and dynamical binary systems at all snapshot intervals is made publicly available.

Charge exchange between highly charged ions and neutral atoms and molecules has been considered as one of the important mechanisms controlling soft X-ray emissions in many astrophysical objects and environments. However, for modeling charge exchange soft X-ray emission, the data of n- and l-resolved state-selective capture cross sections are often obtained by empirical and semiclassical theory calculations. With a newly built cold target recoil-ion momentum spectroscopy (COLTRIMS) apparatus, we perform a series of measurements of the charge exchange of Ne(8,9)+ ions with He and H2 for collision energy ranging from 1 to 24.75 keV/u. n-resolved state-selective capture cross sections are reported. By comparing the measured state-selective capture cross sections to those calculated by the multichannel Landau–Zener method (MCLZ), it is found that MCLZ calculations are in good agreement with the measurement for the dominant n capture for He target. Furthermore, by using nl-resolved cross sections calculated by MCLZ and applying l distributions commonly used in the astrophysical literature to experimentally derived n-resolved cross sections, we calculate the soft X-ray emissions in the charge exchange between 4 keV/u Ne8+ and He by considering the radiative cascade from the excited Ne7+ ions. Reasonable agreement is found in comparison to the measurement for even and separable models, and MCLZ calculations give results in a better agreement.
A Test of the Cosmological Principle with Quasars

Published: February 2021

We study the large-scale anisotropy of the universe by measuring the dipole in the angular distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wide-field Infrared Survey Explorer (WISE). This sample is derived from the new CatWISE2020 catalog, which contains deep photometric measurements at 3.4 and 4.6 μm from the cryogenic, post-cryogenic, and reactivation phases of the WISE mission. While the direction of the dipole in the quasar sky is similar to that of the cosmic microwave background (CMB), its amplitude is over twice as large as expected, rejecting the canonical, exclusively kinematic interpretation of the CMB dipole with a p-value of 5 × 10−7 (4.9σ for a normal distribution, one-sided), the highest significance achieved to date in such studies. Our results are in conflict with the cosmological principle, a foundational assumption of the concordance ΛCDM model.

The following letter, from a network of women zoologists, is a reply to the article of AlShebli et al. (2020), which suggests that female protégés reap more benefits when mentored by men and concludes that female mentors hinder the success of their female protégés and the quality of their impact. This contribution has two parts. First, we highlight the most relevant methodological flaws which, in our opinion, may have impacted the conclusions of AlShebli et al. (2020). Second, we discuss issues pertaining to women in science, bring a perspective of Women in Zoology and discuss how current diversity policies are positively changing our field.
A learning-enhanced projection method for solving convex feasibility problems
Authors: Rieger Janosch
Published: February 2021

We propose a generalization of the method of cyclic projections, which uses the lengths of projection steps carried out in the past to learn about the geometry of the problem and decides on this basis which projections to carry out in the future. We prove the convergence of this algorithm and illustrate its behavior in a first numerical study.
Nonlocal latent low rank sparse representation for single image super resolution via self-similarity learning
Authors: Song Changming , Wang Yun
Published: February 2021

In this paper, we propose a novel scheme for single image super resolution (SR) reconstruction. Firstly, we construct a new self-similarity framework by regarding the low resolution (LR) images as the low rank version of corresponding high resolution (HR) images. Subsequently, nuclear norm minimization (NNM) is employed to generate LR image pyramids from HR ones. The structure of our framework is beneficial to extract LR features, where we regard the quotient image, calculated between HR image and LR image at the same layer, as LR feature. This LR feature has the same dimension as LR image; however the dimension of commonly used gradient feature is 4 times than LR image. On the other hand, we employ nonlocal similar patch, within the same scale and across different scales, to generate HR and LR dictionaries. In the course of encoding, codes are calculated from both row and column of LR dictionary for each LR patch; at the same time, both low rank and sparse constraints on codes matrix give us a hand to remove coding noises. Finally, both quantitative and perceptual results demonstrate that our proposed method has a good SR performance.
Private equity fondovi i hrvatsko iskustvo
Authors:   Croatian Financial Services Supervisory Agency, Derenčinović Morana
Published: February 2021

Private equity funds are important players in the capital market, investing billions of dollars and euros in portfolio companies every year worldwide and in Europe, thus improving their business and development at almost all stages of their life cycle. Although Croatia lags far behind in this respect - both in terms of foreign private equity funds investing in Croatian companies and in terms of developing the private equity industry in Croatia - we believe it is important to analyze private equity funds and their characteristics in order to gain a full understanding of them . Therefore, this paper will try to define private equity funds and private equity and their interconnection, and explain the various forms and types of equity issued in private equity investments. Furthermore, the paper outlines the basic characteristics of private equity funds, which are crucial for understanding the way they operate, the relationship with the portfolio company and investors. Private equity funds have a specific lifespan and term, and bear significant risks (greater than those of the “infamous” hedge funds). They are meant for professional investors whose approach in portfolio companies is “hands on”. The paper also presents the most common structures of private equity funds, which differ significantly from those in Croatia, whose legislative framework unfortunately still places strong legal obstacles for the efficient and effective functioning of private equity funds. Finally, the paper presents the Croatian experience with private equity funds, with a description of the first private equity funds in Croatia and a special reference to economic cooperation funds, as a special feature of the Croatian capital market and private equity industry.
Temeljni prikaz izvedenica uz poseban osvrt na opcije, opcijske i s njima povezane tipske ugovore
Authors:   Privredna banka Zagreb d.d., Ivković Dinko
Published: February 2021

The paper offers a general overview of options within the definition of financial derivatives. The manner of concluding an options contract, its legal characteristics and nature are presented in the light of the Croatian substantive law. In the overview of the types of options, the author analyzes the options prescribed by or incorporated into Croatian laws (e.g. Company Act, Takeover Act, Capital Market Act). After a general presentation and analysis of the ISDA documentation for derivatives, the history, overview and main legal issues related to the Croatian Master Agreement for financial derivatives developed within the Croatian Banking Association and ACI Croatia are elaborated. The analysis conducted in this paper demonstrates that the basic legal institutes on which the ISDA Master Agreement is based are also provided in Croatian law or in applicable EU law. All this leads the author to the conclusion that the Local Framework Agreement for Transactions with Financial Derivatives provides a reasonable tool in terms of significant reduction of legal risks and enables reasonable management of other risks to which contractors are exposed when concluding transactions with derivatives.

Published: February 2021

The study discusses the main positive aspects of the implementation of start-up projects at universities. In the context of the migration of most of the businesses to the network, the most important skill of an entrepreneur is the ability to build an online business from the very first steps. The basis for this is the creation a start-up in e-learning mode. A sample of domestic and foreign universities has been designed to compare new domestic practices with foreign experience of e-learning in entrepreneurship. It has been confirmed that the introduction of start-ups in e-learning mode in the final year of entrepreneurship education positively affects the development of professional qualities of students both in online and off-line business and helps to better consolidate the material. In addition, based on the work done, a final year model of entrepreneurship education with e-learning has been proposed; it is based on 3 main components (the student as a generator of ideas; the mentor as necessary support, and information online channels as the main source of information) and is aimed at solidifying knowledge through the start-up project defense. The importance of the role of universities in this process has been proved and the idea of involving a business mentor in e-learning process to achieve a synergistic effect has been considered.
