This paper presents a two-phase heuristic methodology aimed at the reconfiguration of a radial distribution network with the objective of minimizing the computational time. In the preliminary phase of the operation, all network switches are in a closed state, and it is proposed that a subsequent switch opening methodology be employed to achieve a configuration that approximates optimal radial char

BACKGROUND/OBJECTIVES: Given the risk of a progression, or an undiagnosed endometrial cancer (EC), the treatment of choice is hysterectomy in women with endometrial intraepithelial neoplasia (EIN). The risk of metastatic disease and whether sentinel node (SLN) biopsy should be performed remains unclear. The primary aim of this prospective study was to determine the overall incidence of concurrent

Scholars have shown that lifestyle change is pivotal for any effective climate-mitigation scenario. But what lifestyle changes are needed and how can they be enabled and mainstreamed? This is the question pursued by the EU 1.5° Lifestyles project, the results of which the article summarizes and synthesizes. The project integrated quantitative and qualitative methods, ranging from input-output anal

The Period genes (Per) play essential roles in modulating the molecular circadian clock timing in a broad range of species, which regulates the physiological and cellular rhythms through the transcription-translation feedback loop. While the Period gene paralogs are widely observed among vertebrates, the evolutionary history and the functional diversification of Per genes across vertebrates are no

This master’s thesis has examined the feasibility of an accumulator-based actuation method for the BorgWarner (BW) electric torque vectoring and disconnect (eTVD) system. The requirements for the proposed concepts were defined based on the performance of the baseline eTVD and served as reference criteria throughout the development process. A strong emphasis was placed on reducing system complexit

As the first domestic species, dogs likely dispersed with different cultural groups during the Late Pleistocene and Holocene. To test this hypothesis, we analyzed 73 ancient dog genomes, including 17 newly sequenced individuals sampled from East Asia to the West Eurasian Steppe spanning nearly 10,000 years. Our results indicate correlations between the ancestry of dogs and specific ancient human p

This research examines what was at stake for young Chinese women who are negatively conceptualized as fudimo 扶弟魔. Drawing on feminist theories of everyday resistance and relational autonomy, it explores how they resist intersecting gendered power relations in everyday life. The thesis draws on ethnographic methods, including participant observation and semi-structured interviews with 15 women aged

Wind generation’s growing share of Nordic electricity supply has made imbalance settlement an increasingly costly exposure for producers. Under the Nordic single-price mechanism, all residual imbalance is settled at a single imbalance price, regardless of direction, determined by the mFRR activation market. Before that price is known, the producer fixes a day-ahead position, adjusts on the continu

Gender inequality persists in contemporary Europe despite decades of legal reform. Yet, the emotional bond to the nation may lead women to perceive the unequal gender arrangements as fair and legitimate, a process rooted in system justification motivation. This study examines the association between national attachment and perceived gender fairness among women, and whether this association varies

Bacterial infection and hemorrhage remain significant clinical challenges for chronic wounds, despite advancements in antimicrobial strategies and materials. Herein, 980 nm-laser-responsive photothermal conjugated polymers (CPs) are combined with chitosan-based cryogels (CP@Gel) to achieve rapid hemostasis and efficient anti-infectious performance. CP nanoparticles (CP NPs) were prepared by nanopr

Continuous non-invasive monitoring of respiratory rate in laboratory mice can support research across drug efficacy, sleep, and stress and pain assessment. Established respiratory rate estimation methods exist but many conflict with the 3Rs principle through invasiveness, motion restriction, or animal stress. A cross-method comparison between two non-invasive systems on the same freely-moving anim

The expansion of the European Union's (EU) regulatory sphere creates conflicts of sovereignty between the EU and its member states, and third countries that lack a possibility to participate in the making of those laws and policies. The conflict is epitomised in the concept of the Union's decision-making autonomy. Albeit stringently applied, the concept is ambiguous and undefined. This article end

The Kunming-Montreal Global Biodiversity Framework calls for restoring at least 30% of degraded ecosystems by 2030, while the IPCC and IPBES emphasize restoration as central to addressing climate change and biodiversity loss. Rewilding, defined as the promotion of self-sustaining, complex ecosystems through minimal human intervention, has emerged as a prominent restoration strategy, yet its climat

To determine the variability in fibre areas in the human vastus lateralis muscle, cross-sections (15 microns) of whole autopsied muscles from eight young men have been prepared, and the cross-sectional area (CSA) of 375 type 1 and 375 type 2 fibres has been measured in five different regions throughout each muscle. The CSA of both fibre types varied significantly within all muscle cross-sections.
