Authors: Yang Feng , Wang Zhenbao , Zhang Xianxue 
Published: January 2021

Abstract
Immunotherapy is remarkably affected by the immune environment of the principal tumor. Nonetheless, the immune environment’s clinical relevance in stage IV gastric cancer (GC) is largely unknown. The gene expression profiles of 403 stage IV GC patients in the three cohorts: GEO (Gene Expression Omnibus, GSE84437 (n=292) and GSE62254 (n=77), and TCGA (The Cancer Genome Atlas, n=34) were used in the present study. Using four publicly available stage IV GC expression datasets, 29 immune signatures were expression profiled, and on this basis, we classified stage IV GC. The classification was conducted using the hierarchical clustering method. Three stage IV GC subtypes L, M, and H were identified representing low, medium, and high immunity, respectively. Immune correlation analysis of these three types revealed that Immune H exhibited a better prognostic outcome as well as a higher immune score compared with other subtypes. There was a noticeable difference in the three subgroups of HLA genes. Further, on comparing with other subtypes, CD86, CD80, CD274, CTLA4, PDCD1, and PDCD1LG2 had higher expression in the Immunity H subtype. In stage IV GC, potentially positive associations between immune and pathway activities were displayed, due to the enrichment of pathways including TNF signaling, Th-17 cell differentiation, and JAK-STAT signaling pathways in Immunity H vs Immunity L subtypes. External cohorts from TCGA cohort ratified these results. The identification of stage IV GC subtypes has potential clinical implications in stage IV GC treatment.
Dynamic online joint energy management and sampling rate control in energy harvesting aided IoT network
Authors: Feng Chunhui , Yang Qinghai , Qin Meng , Kwak Kyung Sup 
Published: January 2021

AbstractEnergy harvesting (EH) aided Internet of Things (IoT) network is a promising paradigm to librate IoT network from energy deficiency. Dynamic energy and traffic scheduling in such a scenario is challenging due to temporal correlation of energy constraints and delay requirements of IoT applications. In this paper, joint energy management and sampling rate control to explore the tradeoff between network utility and delay performance are studied while maintaining the energy causality constraint. Taking into account the dynamic characteristics of EH process, channel fading and traffic arrivals, a stochastic optimisation problem is formulated to maximise the network utility. Leveraging the Lyapunov optimisation approach, combined with the idea of weight perturbation, a framework is proposed to decompose the stochastic problem into several deterministic sub‐problems that can be solved separately. Based on the framework, an online resource allocation algorithm is developed to achieve two major goals: first, balancing energy consumption and energy harvesting to stabilise their data and energy queues; second, deriving the utility‐delay tradeoff by adjusting the control parameter. The stability of data buffer and energy buffer in the proposed network is theoretical verified with performance analysis.

Authors: Botlíková Milena , Botlík Josef , Stuchlíková Jana 
Published: January 2021

Research background:With the onset of the Covid-19 pandemic, there has been a complete collapse in demand in global markets due to restrictions on movement and market paralysis. Among the sectors most significantly affected is tourism, which is predominantly dependent on the movement of clients. The performance of the tourism industry fell to a minimum during the pandemic. Restaurants and accommodation facilities were closed almost overnight by government intervention. The restriction of free movement has also forced airlines to curb their activities. These companies can be considered as an important globalization element, enabling travel to distant destinations.Purpose of the article:The article deals with the effects of the pandemic on European Union airlines, as well as the tools adopted to restore air traffic. Based on the analysis, the development of transport flows in air transport before and during the pandemic was evaluated. Furthermore, tools and measures taken to stimulate air services were analyzed and models of possible impacts on the EU aviation industry and selected economic factors were predicted.Methods:Basic mathematical and statistical methods, correlation analysis, comparisons and predictions were used for the analysis.Findings & Value added:The situation brings problems associated with redundancies, i.e. rising unemployment, declining GDP, falling stock markets or airline bankruptcies as in the case of the British Flybe. Based on 2019 data, it can be estimated that in the period March-June 2020, the demand for EU27 passenger air transport decreased by approximately 100 million passengers.

Research background: After the recent restart of global economy, at least in Asia, Europe and U.S., one of the main suffering industries is aviation. As a principal consequence of quarantine and closing borders, most of the people cancelled their flights pushing the airlines companies to the edge of abyss therefore it looks interesting to understand how far they could go and what the operating limit are. If at the moment we have heard news about bankruptcy only about few companies (LGW –a regional German airline and Latam Airlines - South America’s biggest carrier) is because, generally, they still have cash reserves and important demands for help was sent to the governments but the situation is quite dramatic.
Purpose of the article: In this article we will analyse why the aviation sector is facing one of the most complicated times after the 9/11 WTO, what are the main constraints for the industry future and what real measures can be taken in order to recover the situation.
Methods: By means of descriptive and comparative analysis the paper reveals the financial and technical difficulties to implement certain health safety rules imposed by regulators.
Findings & Value added: This new type of pressure caused by Covid-19 pandemic outlines once again the stress in which the aviation sector is found out. Despite the fact that there is a permanent preoccupation to improve technology and performance, governments and health international organisation should take into consideration all the business aspects before launching impossible requests.

The Impact of Globalisation on Value-added Wood Products Trade
Authors: Dzian Michal , Paluš Hubert , Parobek Ján 
Published: January 2021

Research background: The development of the Slovak economy depends on the demand in foreign markets. The Slovak economy is open and responds very sensitively to global changes. Globalisation brings positive as well as negative impacts on national economies. These impacts are also noticeable in the case of value added wood products. Globally, the furniture trade has grown more quickly than furniture production in the last ten years. The value of the world furniture trade has grown by 65%. On the other hand, domestic sales of furniture are low due to the orientation of the Slovak furniture producers on export, even if at the present time the positive development is reflected in an increasing total sales volume.
Purpose of the article: This paper is focused on the assessment of globalisation impact on value added wood products trade. The aim of the paper is to determine the relationship between the trends of globalisation and furniture trade in Slovakia.
Methods: The development of foreign furniture trade in Slovakia was analysed. In addition, the development of the KOF globalisation index was examined in the period from 2001 to 2017 by applying the linear regression and correlation analysis.
Findings & Value added: Based on the analysed results, a positive linear relationship between the development of furniture trade in Slovakia and globalisation was observed. The results further show that the impact of globalisation is more significant in the case of export of furniture rather than its import.
Accounting and tax accounting for the accrual of depreciation of fixed assets and ways of convergence
Authors: Hajiyev Hafis 
Published: January 2021

Research background: As you know, one of the main accounting principles that determine the methodology for assessing the facts of economic life is business continuity. Compliance with this principle by commercial organizations is associated with many factors, one of which is their ability to provide funding for the continuation and development of activities. Carrying out activities for the acquisition of new or modernization and technical re-equipment of existing fixed assets implies one-time cash costs. That is why one of the main sources of financing for updating and modernization and technical re-equipment of fixed assets is depreciation deductions. Depreciation deductions for fixed assets in accounting and tax accounting are calculated differently, which determines the relevance and need for a clear study of accounting procedures in the field of their accounting.
Purpose of the article: The purpose of the article is to conduct a comparative analysis of the procedure for calculating and accounting for depreciation deductions for fixed assets in accounting and tax accounting and to study ways to bring them closer together.
Methods: Methods of comparative analysis, induction and deduction were used in the article.
Findings & Value added: The current rules for calculating depreciation deductions for fixed assets and their reflection in accounting and reporting do not provide a reliable reflection of the facts of economic activity of the enterprise. And this in turn leads to a misunderstanding by the respective users of the contents of the statement of financial position and the statement of profit or loss and other comprehensive income and the essence of depreciation itself.
