Platelet RNA Sequencing Data Through the Lens of Machine Learning
PublikacjaLiquid biopsies offer minimally invasive diagnosis and monitoring of cancer disease. This biosource is often analyzed using sequencing, which generates highly complex data that can be used using machine learning tools. Nevertheless, validating the clinical applications of such methods is challenging. It requires: (a) using data from many patients; (b) verifying potential bias concerning sample collection; and (c) adding interpretability...

A systematic review on cellular responses of Escherichia coli to nonthermal electromagnetic irradiation
PublikacjaInvestigation of Escherichia coli under electromagnetic fields is of significance in human studies owing to its short doubling time and human‐like DNA mechanisms. The present review aims to systematically evaluate the literature to conclude causality between 0 and 300 GHz electromagnetic fields and biological effects in E. coli. To that end, the OHAT methodology and risk of bias tool were employed. Exponentially growing cells exposed...

How Small KIBS Companies Manage Their Intellectual Capital? Towards an Emergent KM Approach
PublikacjaThe growing interest in Intellectual Capital management and Knowledge Management is now reaching small companies, especially those in the Knowledge-Intensive Business Services (KIBS) sector. This paper aims to explore this issue, starting from the assumption that a planned and systematic approach to KM, as is used in large companies, is rarely applicable in small organizations. It is more likely that small companies adopt an approach...

From the Concept to Results: A Case Study on the Collection Development for the ODC–Opening Day Collection at Qatar National Library
Publikacja"A library collection should fit the mission for which it is created. The number of books it holds does not determine its worth." (E. J. Loveland, 2000) If so, how do we create a national library, and how do we build its collection from scratch without making many mistakes? Since 2012, when the plans for the new national library were announced, Qatar National Library (QNL) envisioned as carrying out its mission to "spread knowledge,...

Precise Point Positioning Method Based on Wide-lane and Narrow-lane Phase Observations and Between Satellites Single Differencing
PublikacjaThe issue of using PPP method in position determination was formed in 1997. In most developed methods, ionospheric-free linear combination is used in order to eliminate the impact of the ionospheric delay. However, this approach does not provide the directly determination of the total value of the ambiguities, and the ambiguities for the individual signals. Therefore, in many publications methods of avoiding these deficiencies...
