AIM: to assess the length of the stump of the feeding arteries of the right colon, their anatomical location relative to the superior mesenteric vein (SMV), the level of ligation of the main arteries after right hemicolectomy with D2- and D3-lymphadenectomy.

   PATIENTS AND METHODS: the retrospective study included 82 patients with a histologically confirmed right colon cancer aged 44-88 (mean 68) years. All patients underwent right hemicolectomy. In 40 cases, D2 lymph node dissection was performed, in 42 cases — in D3. Preoperatively, all patients were assessed for the location of the ileocolic and right colon arteries relative to the SMV and the expected length of their stumps was measured by CT. Postoperatively, the actual length of the stumps was assessed.

   RESULTS: CT images of the ileocolic artery stump were obtained in 76 (92.6%) of 82 patients. In 6 patients, a metal clips were installed along the contour of the superior mesenteric artery; in such cases, a clear CT image of the stump of the ileocolic artery was not obtained, and the length of the stump was assessed as 0 mm. The stump of the right colic artery was determined in all patients in whom the artery was identified preoperatively. The ventral location of the ileocolic artery relative to the SMV according to CT data was identified in 38 (46.3 %) of 82 patients, the dorsal location — in 44 (53.7 %) of 82 patients. With the ventral location of the ileocolic artery relative to the SMV in patients with D2, the length of the artery was 14.3 (8-25.6) mm, with D3 — 7.6 (3.3–11.1) mm (p = 0.005). With the dorsal location of the ileocolic artery relative to the SMV in patients with D2, the length of the artery was 8.8 (4.9–16.2) mm, with D3 — 3.9 (1–6.9) mm (p = 0.004).

   CONCLUSION: the actual length of the stump of the feeding artery can become an indicator of the level of ligation of the main arteries and, indirectly, the extent of lymphadenectomy after right hemicolectomy. Further studies with a larger number of cases are needed to confirm the hypothesis for measuring the length of the stump of the feeding arteries as a marker of the extent of the procedure performed.
PERFORMANCE ANALYSIS OF ADAPTIVE FILTER AND FIR WIENER FILTER FOR NOISE CANCELLATION IN AUDIO SIGNALS
Authors: Saeed Awais , Khalid Abdullah , Fatima Mahvish
Published: August 2024

Speech has always been one of the most important carriers of information for people and has become a challenge to maintain its high quality. When the speech signal and noise both change continuously, then arises the need for algorithm that will form best estimation of noise signal. In Adaptive Noise Cancellation and Wiener Noise Cancellation two inputs - primary and reference signals are used. The primary input receives signal from the signal source which has been corrupted with a noise uncorrelated to the signal. The reference input receives noise signal uncorrelated with the signal but correlated in some way to the noise signal in primary input. The reference input is filtered to obtain a close estimate of primary input noise which is then subtracted from the corrupted signal at the primary input to produce an estimate of a clean uncorrupted signal. The audio signal corrupted with noise is used as a primary input and a noise signal is used as reference input. Computer simulations are carried out using MATLAB and illustrated.

Authors: Hanif Rahila , Choudhary Sadaf , Ismail Aisha
Published: August 2024

The continuous development in the asset pricing is providing new empirical models and techniques to check the relationship between risk and return on stocks but it might be challenging to pick one model to use for the users. Investors and investment portfolio managers are always in search of such financial models that may quantify risk in an appropriate manner and can translate the risk into expected returns on equity investment options. Different models and techniques have been applied by the researchers and analysts from time to time to analyze this relationship; among them CAPM is the most famous and widely used technique. Later on, [1] extended the CAPM by adding two more factors in it; Size and Value. Subsequently, [2] introduced Five-Factors Pricing Model (FF5F); which is a development of the earlier models, by adding two new factors; investment level and profitability position. This study is intended to investigate whether a Fama and French five factor asset pricing model (FF5F) can explain average returns of stocks on Pakistan stock exchange (PSX) in a better way than the three factor model (FF3F) and CAPM or there is a need to include more factors in it. The study will be conducted on a sample of all listed non-financial firmsâ€™ stock with persistent trading on the PSX by constructing portfolios based upon basic factors identified by [3]. The analysis will be performed by regression analysis. This study will be helpful to the investors, investment advisers and fund managers to entrench their operating strategies and methodologies by adding the expounding power of size, beta, and value along with the momentum of portfolio returns to allow them to devise some trading policies to minimize losses and to maximize returns. In addition to this, policy makers can ensure that some proper measures are already in place to improve market liquidity and viability to improve the breadth and depth of the whole market.

Published: August 2024

Ford and Moghrabi [2] introduced the multi-step quasi-Newton method for optimization, Where Hessian matrix is updated for each iteration, this make it computationally expensive. To overcome this problem Jhon and Nudrat [4] introduced a multi-step skipping technique, which shows a better experimental results. In Ford and Moghrabi, papers series, they introduced some techniques (Accumulative and Fixed-point approaches) to describe the parametric values needed to figure out the distances between many sets of iterations being involved in the recent interpolation curve.In this thesis, we extended the existing three-step Fixed-point skipping approach and examine the sensitivity of this technique. Evidently, experimental result provides, positive improvement with comparison to standard Broyden-Fletcher-GoldfrabShanno (BFGS) method. Result shows comparatively, three-step Fixed-point skipping technique computational saves time than existing single-step BFGS method

Authors: Cikal
Published: August 2024

On a practical level, market positioning is critical to achieving competitive advantage, and thus the success of new ventures and entrepreneurs needs more relevant insights to help them gain a foothold in new or existing markets. The purpose of this paper is to carefully analyze and assess the current body of written work regarding the strategic act of positioning a product or brand in the market, thereby critically reassessing and re-evaluating the fundamental notion of positioning and ultimately establishing a more all-encompassing and thorough definition from an abstract and theoretical point of view. In this paper, the authors would like to explore past research related to market positioning in the Scopus database using the keywords “positioning marketing", marketing positioning”, "positioning”, and “strategic positioning” from 2000–2023 (23 years) using the criteria of “exclude and include,” and a total of 140 articles were obtained. Once analyzed, the literature review revealed that there is no coherent definition for positioning and that there is no common agreement among marketing experts and practitioners on the precise meaning of the concept. Therefore, a comprehensive definition of positioning covering the five underlying positioning perspectives (competition, gap/empty mind, consumer perception, differentiation, and advantage) is suggested.
Keywords: Market Positioning, Positioning Strategy, Bibliometric Analysis.

Authors: Shkilniak Kostyantyn
Published: August 2024

Introduction. Nowadays, more and more attention is paid to the problems of digitalization of the economy, the characteristic features of which are the process during which the electronic information environment develops and the latest technologies. Under current conditions, Ukraine is the only one among European states that does not have sufficient digital resources for its complete transfer to the rails of the digital economy. Not the biggest reason why this process slowed down was the full-scale invasion and hostilities, due to which the Ukrainian economy has significant costs (losses), as well as the process that would allow it to transform into the latest digital environment. Because of such trends, there is an urgent need to identify the current problems of the process during which the Ukrainian digital economy is being formed, the main trends and perspectives of how it should develop, moving in the direction of European integration, are maturing.
Purpose. The purpose of the article is to reveal the theoretical foundations of the modern paradigm of digitalization of the Ukrainian economy.
Methods. In the process of writing this article, the following methods were used: methods of analysis and synthesis (for the purpose of a thorough study of the essence of digitalization of the economy), a graphic method (for the purpose of providing the main definitions of this concept by various Ukrainian scientists), a generalization method, a complex and systematic approach, and an abstract-logical method (for the purpose of formulating conclusions and prospects for further research).
Conclusions. The essence of the concept of “digital economy” is revealed and it is determined that it is expedient to consider it as a separate sector of the economy, where business entities conduct economic activity using information and communication and digital technologies, and the leading means (factors) of production are digital (electronic, virtual) data (numerical and text). At the same time, it was established that digitalization should be understood as a process related to the active formation, use, and improvement of technologies specializing in information and communication content.
Discussion. Prospects for further research are the study of modern trends in the use of information and communication technologies during digitalization, which has been actively gaining momentum in recent years.
