This research monograph explores new frontiers in Markov chains. Although time-homogeneous Markov chains are well understood, this is not at all the case with time-inhomogeneous ones. The book, after a review on the classical theory of homogeneous chains, including the electrical network approach, introduces several new models which involve inhomogeneous chains as well as related new types of rand

This thesis investigates the role of trust in the context of decentralised finance (DeFi). Representing a new paradigm shift in finance, DeFi emerge from the technological developments that we have witnessing in the last decades, particularly decentralised ledger technologies (DLTs) of which Blockchain is perhaps the most popular. DeFi is changing the way that firms raise financial capital and a c

The purpose of this thesis’ topic is to investigate the evolutionary dispersal of the Charon’s fee or Obolus rite outside the Roman provinces in Northern Europe, with a specific focus on Roman Iron Age and Migration Period Scandinavia. The aim of this study is therefore to add further understanding to the spread of Roman cultural influences outside the imperial borders and what made Roman material

Bacterial infections represent a serious health care problem, and all multicellular organisms have developed defense mechanisms to eliminate pathogens that enter the host via different paths including wounds. Many invertebrates have an open circulatory system, and effective coagulation systems are in place to ensure fast and efficient closure of wounds. It was proposed early on that coagulation sy

Climate change poses a significant threat to global stability, with rising temperatures leading to severe environmental and economic impacts. In response, innovative policy mechanisms such as the Global Carbon Reward (GCR) have been designed to enhance the effectiveness of carbon pricing strategies. The foundational aspect of the GCR is a carbon reward, which acts as a financial incentive distribu

I den pågående kampen mot klimathotet har Europeiska unionen antagit en ledande roll för att fullfölja skiftet mot en grön ekonomi, bland annat genom att fokusera på att stärka konkurrenskraften avseende tillverkningen av netto-noll energiindustrin och säkra de nödvändiga råvarorna för denna omställning. För att möjliggöra detta presenterade den Europeiska kommissionen i mars 2023, i samband med pIn the global race against climate change, the answer of the European Union is the transition towards a green economy by focusing on strengthening the competitiveness of the net-zero technology industry and securing the necessary critical materials. To do so, the Union presented two legislative acts in the European Green Deal Industrial Plan in 2023, amongst which the Net-Zero Industry Act. While

Adopting a qualitative approach to the investigation of high achievement, the authors analyzed how high-achieving women in the Swedish workplace made meaning of positive and negative experiences in their work. The data consisted of interviews with 15 women identified as being high achieving in their respective field, and it was analyzed using grounded theory methodology. The women described five d

Pituitary adenohypophyseal tumors are considered as benign and termed “adenomas”. However, many tumors are invasive and a proportion of these exhibit an “aggressive behavior” with premature death due to progressive growth. Only very rare (0.2%) tumors with metastases are considered malignant and termed “carcinomas”. Taking into account this variability in behavior and the oncological definition, p

Soft tissue sarcoma (STS) diagnostics and prognostics are challenging, particularly in highly malignant and pleomorphic subtypes such as undifferentiated pleomorphic sarcoma (UPS) and leiomyosarcoma (LMS). We applied 32K BAC arrays and gene expression profiling to 18 extremity soft tissue LMS and 31 extremity soft tissue UPS with the aim of identifying molecular subtype signatures and genomic prog

Evaluating the trade interdependence among countries is the key to understanding critical metal minerals security. By constructing a novel interdependence network, this paper reveals a more comprehensive world hierarchy and risk system of critical metals, and focuses on the interdependencies between China and the US-led MSP countries before and after the Sino-US trade disputes. The results indicat

Four organizations at Stockholm-Arlanda airport are going through various organizational changes. They are preparing for present and future demands through structural changes, implementation of new technology, training, and other efficiency and capacity improving measures. The change processes will be followed during two years of which this paper presents the baseline measurement. The key factors

The properties of the bootstrap test for restrictions are studied in two versions: 1) bootstrapping under the null hypothesis, restricted, and 2) bootstrapping under the alternative hypothesis, unrestricted. This article demonstrates the equivalence of these two methods, and illustrates the small sample properties of the Wald test for testing Granger-Causality in a stable stationary VAR system by

Increased use of powerful PCR technology for the routine detection of pathogens has focused attention on the need for international validation and preparation of official non-commercial guidelines. Bacteria of epidemiological importance should be the prime focus, although a "validation infrastructure" once established could easily be adapted for PCR-based detection of viruses and parasites. The ai

The aim of this paper is to study the extent to which non-Annex I countries are implementing or exploring select actions that support both climate change mitigation and sustainable development objectives in the energy sector. The research is based on a survey of the national communications of 100 non-Annex I Parties to the UNFCCC. Although national communications are intended to provide informatio
