The purpose of the article is to determine the stages of development of music broadcasting and to reveal their features in the context of the evolution of audio recording means. The methodology consists of the application of general scientific and special methods, namely: information and system approaches, terminological and historical methods, as well as methods of analysis and generalization of source information, comparison and interrelation of theory and practice. Scientific novelty. The significance of musical resources has been brought to the development of radio communications and the early stages of development of musical radio communications have been clarified in the context of the evolution by means of audio recording. Conclusions. Radio has played one of the leading roles in the field of music and, conversely, without music, radio broadcasting has not received the appropriate technical development and, accordingly, would not have had such an impact on society. Clusters of music radio recordings on the rights of subsystems are connected to the metasystem of information communications. Music publishers, who were then the most influential part of the industry, allied with the musicians. At the time of birth, radio notes were the main musical product, and songwriters were real stars. However, when the whole world began to buy records instead of music, the power from publishers and singers passed to record companies and cooperated with them performers. In the early stages of its existence, musical radio broadcasting underwent an evolutionary path from the musical telegraph (1876), the first radio shows with magnetic recording (1914), the rapid development of radio engineering and recording technology (1920–1940), and 3-minute rock ‘n’ roll from artisanal records (1950s) to «pirate music», which was broadcast from ships (1960s). The study of the historical and cultural preconditions for the formation and development of musical radio broadcasting at an early stage in the context of the evolution of audio recording allowed to identify three main stages: «search» (1870–1920), 2) «competitive» (early 1920s – second half of the 1940s). .), 3) «vinyl-tape» (first half of the 1950s – 1970s). The term «music broadcasting» is proposed to mean technological means of sound transmission to an unlimited number of listeners of musical compositions and / or other musical information on the radio, as well as wired radio networks or packet-switched networks, classifying them as «active phonograms». , broadcast) and «passive phonograms» (performed a functional role and transferred to the archive).

Stage Of Development

It is impossible to imagine the development of high-tech sectors of the Russian economy without the emergence and active growth of a large number of small innovative enterprises that create and promote demanded competitive goods and services on the Russian and international markets. The development of this type of company often requires the attraction of so-called “comfortable” venture capital. The main source of such capital in the early stages of development of small innovative companies is business angels. However, the evaluation of innovative projects at an early stage of development and the decision-making of business angels about investing is a rather time-consuming process, involving the analysis and systematization of a huge amount of information.The article proposes 56 criteria for evaluating innovative projects of early stages of development. The criteria have been divided into 8 groups specific to the evaluation of projects. These criteria typically use grading scales. The most commonly used are 10-point, 5-point, 100-point rating scales and 0…1 scale.It was proposed to evaluate innovative projects of the early stages of development not only according to the rating scale, but also using colors. Red (for negative assessments) and blue (for positive assessments) colors gradients have been used in the article. An example of constructing a colorographic map based on a fictional innovative project has been adduced. The developed colorographic maps will allow the investor to evaluate visually the information on the investment application submitted for consideration using a two-dimensional image (this is essentially a table).The visualization of project estimates in the form of a colored octahedron has been presented. In constructing the octahedron, red, blue and white (no grade) gradients were also used. Each face of the octahedron corresponds to a group of criteria of this project. The criteria in the group are located in such a way that when reflected on the plane they will be located closer to the center of the octahedron. Thus, in the case of saturated color of the center of the octahedron, the project can receive either an excellent, or unsatisfactory rating. This visualization of the project can be useful if you need to analyze each group of criteria separately.

Abstract: Using a comprehensive database with 51 emerging countries studied over a 13 year period, we find that devaluation increases the PE investment. More years of annual devaluation have a higher impact in promoting PE investment. Conclusions are confirmed for total and high technology PE investments, but not for early stage PE investments. Devaluation does not benefit PE investment in firms in the early stages of development. Devaluation itself is not sufficient to encourage the appetite of investors; however, some country-level competitiveness variables are indispensable for making a country more fertile for PE investment when a devaluation occurs – the high relevance of competiveness increasing in the long term.

The aim of the paper is to verify if equity crowdfunding has an impact on equity gap reduction among early stage companies in Poland. The analysis is based on crowdfunding campaigns organized on the three most popular platforms in Poland during the 2015–2019 period. The presented research on equity crowdfunding allowed the main goal of the paper to be accomplished, namely to characterize equity crowdfunding in Poland. The results obtained also enabled equity crowdfunding to be placed among other equity capital sources for companies in the early stages of development. The results of the study verify the hypothesis that equity crowdfunding has an impact on equity gap reduction among Polish early stage companies. Our key findings prove that equity crowdfunding in Poland is mainly used by relatively small, early stage companies that operate in various sectors. Another finding is that most of the companies raised capital that qualifies as the Macmillan gap. We also proved that there is a relatively high level of information asymmetry among equity crowdfunding campaigns and provided our own definition of equity crowdfunding.

With the rapid development of the logistics industry, the demand of customer become higher and higher. The timeliness of distribution becomes one of the important factors that directly affect the profit and customer satisfaction of the enterprise. If the distribution route is planned rationally, the cost can be greatly reduced and the customer satisfaction can be improved. Aiming at the routing problem of A company’s vehicle distribution link, we establish mathematical models based on theory and practice. According to the characteristics of the model, genetic algorithm is selected as the algorithm of path optimization. At the same time, we simulate the actual situation of a company, and use genetic algorithm to plan the calculus. By contrast, the genetic algorithm suitable for solving complex optimization problems, the practicability of genetic algorithm in this design is highlighted. It solves the problem of unreasonable transportation of A company, so as to get faster efficiency and lower cost.

AbstractPlatelets have an important role in tumor angiogenesis, growth, and metastasis. The reciprocal interaction between cancer and platelets results in changes of several platelet characteristics. It is becoming clear that analysis of these platelet features could offer a new strategy in the search for biomarkers of cancer. Here, we review the human studies in which platelet characteristics (e.g., count, volume, protein, and mRNA content) are investigated in early-stage cancer. The main focus of this paper is to evaluate which platelet features are suitable for the development of a blood test that could detect cancer in its early stages.

Abstract Background Hepatocellular carcinoma and hepatitis C are strongly associated. The current work aimed to study the expression levels of microRNA-331-3p and microRNA-23b-3p as propable biomarkers for detecting liver cancer (HCC) at its early stages in patients with HCV-related liver cirrhosis. The current prospective study included two hundred participants, divided into three groups: group I, 100 patients with HCV-related liver cirrhosis; group II, 50 HCC patients at early stages; and group III, 50 apparentlyhealthy controls. All patients had routine laboratory workup and ultrasound hepatic assessment. Values of microRNA-331-3p and microRNA-23b-3p were measured by real-time quantitative PCR. Results Levels of miR-331-3p were significantly higher in HCC patients than in cirrhotic patients and controls (p < 0.001), while levels of miR-23b-3p were significantly lower in HCC patients compared to cirrhotics and controls (p < 0.001). ROC curve revealed that miR-23b-3p had 80% sensitivity and 74% specificity, miR-331-3p had 66% sensitivity and 61% specificity, and AFP had 64% sensitivity and 61% specificity of 61% in discrimination between HCC patients from controls. Conclusion Serum miR-23b-3p is a more effective predictor than miR-331-3p and AFP for the development of hepatocellular carcinoma in hepatitis C (HCV)-related cirrhotic patients.

Myriophyllum aquaticum (Vell.) Verdc. produces two morphologically different forms of leaves based on whether they are aerial or aquatic. The objective of this study was to determine whether there are any similarities or differences between these two growth forms during their early stages of development. A comparative developmental study of aerial and aquatic growth forms of M. aquaticum was conducted from a qualitative and quantitative perspective using a scanning electron microscope. The pattern of leaf and lobe initiation such as their origin and shape were similar in both growth forms until the fourth plastochron (stage P4). Differences between the two growth forms became evident from stage P5 onward, where a larger shoot apical meristem (SAM), elongated epidermal cells, shorter and slightly more numerous lobes, as well as the presence of appendage-like structures characterized aquatic growth forms. On the other hand, aerial growth forms had smaller SAM, bulb-like epidermal cells, and longer and slightly less numerous leaf lobes. Significant differences between growth forms were noted for parameters such as volume of SAM, length of terminal, first, and middle lobes, as well as the length from first to last lobes. The volume of the SAM of aquatic shoot tips was always greater than aerial forms. On the other hand, lobes of aerial forms were always longer than the aquatic counterpart during early stages of development. This study on the development of M. aquaticum shows that the aerial and aquatic growth forms diverge from their early stages of development.
