Retrospective comparative analysis of two medical evacuation systems for Ukrainian patients affected by war.

Introduction: Coordinated medical evacuations represent an important strategy for emergency response when healthcare systems are impaired by armed conflict, particularly for patients diagnosed with life-threatening conditions such as cancer. In this study, we compare the experiences of two parallel medical evacuation systems developed to meet the medical needs of Ukrainians affected by war.

Methods: This retrospective study compared outcomes of two medical evacuation systems, developed by the European Union Emergency Response Coordination Centre (ERCC) and Supporting Action for Emergency Response in Ukraine (SAFER Ukraine) collaborative, in the first 10 months after the war's intensification in Ukraine (February 24 to December 21, 2022).

Personality and Risk-Perception Profiles with Regard to Subjective Wellbeing and Company Management: Corporate Managers during the Covid-19 Pandemic.

This study examined the role of the Big Five personality traits and risk perception profiles among a sample of corporate managers concerning their subjective wellbeing (SWB) and corporate management practices during the Covid-19 pandemic. Two hundred and fifty-five chief executive officers (CEOs) and chief financial officers (CFOs) of companies listed on the main market of the Warsaw Stock Exchange (WSE) in Poland participated in the study by completing the Satisfaction with Life Scale, Positive and Negative Affect Scale, Ten-Item Personality Inventory, Stimulation-Instrumental Risk Inventory, and a business survey on the Covid-19 pandemic's impact on company management. Latent profile analysis revealed the existence of diverse profiles among the participants regarding personality traits and risk perception, which were variously related to their SWB and managerial practices during the pandemic.

Managerial overconfidence in capital structure decisions and its link to aggregate demand: An agent-based model perspective.

Objective: This study aims to connect two strands of the psychology and economics literature, i.e., behavioural finance and agent-based macroeconomics, to assess the impact of managerial overconfidence at the micro and macro levels of the economy as a whole.

Enzymatic Platforms for Sensitive Neurotransmitter Detection.

A convenient electrochemical sensing pathway was investigated for neurotransmitter detection based on newly synthesized silole derivatives and laccase/horseradish-peroxidase-modified platinum (Pt)/gold (Au) electrodes. The miniature neurotransmitter's biosensors were designed and constructed via the immobilization of laccase in an electroactive layer of the Pt electrode coated with poly(2,6-bis(3,4-ethylenedioxythiophene)-4-methyl-4-octyl-dithienosilole) and laccase for serotonin (5-HT) detection, and a Au electrode modified with the electroconducting polymer poly(2,6-bis(selenophen-2-yl)-4-methyl-4-octyl-dithienosilole), along with horseradish peroxidase (HRP), for dopamine (DA) monitoring. These sensing arrangements utilized the catalytic oxidation of neurotransmitters to reactive quinone derivatives (the oxidation process was provided in the enzymes' presence).

Surface topography analysis with application of roughness area dependence method.

At the moment the root mean square roughness (R) is the most commonly used parameter for quantitative description of surface properties. However, this parameter has one main disadvantage: for its calculation only height variations of surface profile are used which are then represented by a single number. To eliminate this restriction authors of the paper have developed a surface analysis method which is based on roughness calculation in the function of gradually increasing dimensions of a sampling area.
